Verdict-driving rules — more tips below
How to read the scores in this report. There is one headline number — Capture Health above — which reflects how the game actually ran during this session. The other scores further down are drill-downs that each measure a different axis and are not expected to equal Capture Health:
- Gaming Setup Score — how well your Windows/hardware is configured for gaming (ReBAR, HAGS, power plan, drivers). A config rating, not this session's result.
- Pre-Game Health — a pre-flight static check of drivers/config before you play. It doesn't see this session at all.
- Priority Rules — the count of high-priority rules that drive the verdict above. It is not the total of every tip in the report — lower-priority config suggestions (HAGS, Game Mode, PCIe link, RAM kit, etc.) are listed further down as quick wins.
Results disclaimer: Performance outcomes vary by hardware, game build, drivers, background load, thermal state, and applied settings. Values shown are measured for this capture and are not guaranteed future results.

Top 3 Actions
Ranked across every check by measured impact — do these first. Hover a card to see why it ranked.
1
GPU is overheating and thermal throttling
Critical impact
High confidence
Cool the GPU: clear dust, raise the fan curve (e.g. MSI Afterburner), improve case airflow, and cap the frame rate or lower one heavy setting. Full step-by-step guidance is in Your Game Plan below.
2
Graphics card is not getting its full PCIe lane width
High impact
Moderate confidence
Seat the card in the top x16 slot, and in BIOS enable 'Above 4G Decoding' and 'Resizable BAR'. Full steps are in Your Game Plan below.
3
Virtualization-Based Security / Memory Integrity is on
Medium impact
Moderate confidence
Settings → Core isolation → turn off Memory Integrity (weigh the security impact). Some competitive anti-cheats require it — leave on if so.
Confidence reflects how strongly the telemetry supports each finding — it is a qualitative signal strength, not a performance guarantee. Full step-by-step guidance is in Your Game Plan below.
🎮 Your Game Plan
Plain-English summary and step-by-step fixes — start here if you're not sure what to change.We found a few things slowing your games down. Let's fix them.
Your average frame rate was about 49 FPS, dipping to roughly 36 FPS in the rough patches.
We found 2 main issues to fix and 4 quick optimizations. They're listed below, most important first.
1
Cool down your graphics card
Your GPU reached 88°C while gaming. When it gets this hot it deliberately slows itself down to avoid damage, which costs you FPS and causes stutters.
Do this:
- Make sure your PC has room to breathe — keep it off carpet and away from walls.
- Gently clean dust from the case fans and graphics card with compressed air (PC off and unplugged).
- In MSI Afterburner (a free tool), raise the fan speed a little or set a steeper fan curve.
- If it is still hot, lower one or two heavy settings in-game (shadows, ray tracing).
✅ Check it worked: Re-run Arbiter while gaming — the GPU temperature should stay under about 80°C and the thermal-throttling warning should disappear.
⏱ 10–20 min
🔧 Medium
🎯 High impact
⚠️ Low risk
🔁 Reboot: No
2
Give your graphics card its full lane width
GPU is capable of x16 but is currently linked at x8 (~50% PCIe bandwidth reduction). Confirm the GPU is in the primary x16 slot, review BIOS PCIe / bifurcation settings, and check whether an M.2 drive is sharing the GPU's lanes.
Do this:
- Power off and unplug the PC, then open the side panel.
- Make sure the graphics card is in the top PCIe slot (closest to the CPU) — that is the full-speed x16 slot.
- If you have an M.2 SSD, check your motherboard manual: some M.2 slots borrow lanes from the graphics card. Moving the SSD to a different M.2 slot can free them.
- In BIOS, enable 'Above 4G Decoding' and 'Resizable BAR', and set the main slot to x16 if the option exists.
✅ Check it worked: Re-run Arbiter — the GPU's PCIe slot on the hardware map should turn green and read x16.
⏱ 15–30 min
🔧 Advanced
🎯 High impact
⚠️ Medium risk
🔁 Reboot: Yes
3
Virtualization-Based Security / Memory Integrity is on
VBS and HVCI (Memory Integrity) virtualize parts of the kernel for security. This is good for safety but measurably taxes CPU-bound games (often 5-10%+). Only disable it if you understand the security trade-off and your anti-cheat doesn't require it.
Do this:
- Settings -> Core isolation -> turn off Memory Integrity (weigh the security impact)
- Some competitive anti-cheats require it — leave on if so.
✅ Check it worked: Re-run Arbiter — this finding should clear from the OS Diagnostics panel.
⏱ 5–15 min
🔧 Medium
🎯 Medium impact
⚠️ Low risk
🔁 Reboot: Yes
4
Heavy startup-app load
Several resource-heavy apps launch at startup and keep running in the background during gameplay, consuming RAM, CPU and disk.
Do this:
- Open Task Manager -> Startup apps and disable anything you don't need at boot (launchers, sync clients, RGB/monitoring utilities).
✅ Check it worked: Re-run Arbiter — this finding should clear from the OS Diagnostics panel.
⏱ 5–15 min
🔧 Medium
🎯 Medium impact
⚠️ Low risk
🔁 Reboot: No
5
Turn on Windows Game Mode
Game Mode tells Windows to prioritise your game and hold back background tasks and updates while you play.
Do this:
- Press the Windows key and type 'Game Mode settings'.
- Switch Game Mode to On.
✅ Check it worked: Re-run Arbiter — Game Mode should show as Enabled.
⏱ 30 sec
🔧 Easy
🎯 Medium impact
⚠️ Low risk
🔁 Reboot: No
6
Turn on Hardware-Accelerated GPU Scheduling
This lets your graphics card manage its own work more directly, which can shave off a little input lag.
Do this:
- Press the Windows key, type 'Graphics settings', and open it.
- Turn on 'Hardware-accelerated GPU scheduling'.
- Restart the PC.
✅ Check it worked: Re-run Arbiter — HAGS should show as Enabled.
⏱ 2 min
🔧 Easy
🎯 Low impact
⚠️ Low risk
🔁 Reboot: Yes
After you make a change, run Arbiter again and compare — fixed issues should disappear and your scores should climb. ⬆️

● Virtualization-Based Security / Memory Integrity is on
Security↻ Reboot
VBS and HVCI (Memory Integrity) virtualize parts of the kernel for security. This is good for safety but measurably taxes CPU-bound games (often 5-10%+). Only disable it if you understand the security trade-off and your anti-cheat doesn't require it.
🔎 VBS=on, HVCI=on
Fix: Settings → Core isolation → turn off Memory Integrity (weigh the security impact). Some competitive anti-cheats require it — leave on if so.
● Heavy startup-app load
Startup
Several resource-heavy apps launch at startup and keep running in the background during gameplay, consuming RAM, CPU and disk.
🔎 3 high-impact of 11 startup entries: OneDrive, Battle.net, SteelSeriesGG
Fix: Open Task Manager → Startup apps and disable anything you don't need at boot (launchers, sync clients, RGB/monitoring utilities).
● WMI activity storm during gameplay
Services
A high volume of WMI activity occurred during gameplay. Management/monitoring agents (OEM utilities, RGB software, some anti-cheat and enterprise tools) can hammer WMI and cause periodic CPU spikes and hitching.
🔎 1,416 WMI operations · top consumer powershell (1,181)
Fix: Identify the noisy app (often OEM/RGB/monitoring software) and close it before gaming, or disable its background service.
● Network adapter power saving is enabled
Network
'Allow the computer to turn off this device to save power' can introduce micro-drops and latency spikes on Wi-Fi/Ethernet, which show up as lag or rubber-banding in online games.
🔎 Power saving on: Ethernet 2
Fix: Device Manager → your network adapter → Properties → Power Management → uncheck 'Allow the computer to turn off this device'.
● USB Selective Suspend is enabled
Device
Windows can power down USB devices it thinks are idle. For gaming this occasionally resets or briefly drops a controller, mouse or headset, feeling like input lag or a device hiccup.
🔎 DisableSelectiveSuspend is not set (power saver active)
Fix: Device Manager → each USB Root Hub → Power Management → uncheck 'Allow the computer to turn off this device', or disable USB selective suspend in the advanced power plan settings.

ℹ️ Game folder not excluded from real-time antivirus
Security
Real-time scanning can add disk latency when a game streams assets. Adding the game's folder as an exclusion can reduce texture-streaming hitches. Only exclude trusted game folders.
🔎 No Defender exclusion matched diablo iv.exe
Fix: Windows Security → Virus & threat protection → Exclusions → add your game's install folder (trusted titles only).
These findings cover both game-specific and whole-PC issues that slow the machine — driver DPC latency, GPU driver resets, background service/WMI storms, device resets, crashes, outdated drivers, heavy startup load, low disk space or a failing/HDD system drive, memory pressure, background CPU hogs, and configuration such as Memory Integrity, page file, HPET and antivirus. Always weigh security trade-offs before disabling protections.

🎮 GPU Diagnostics — Your Graphics Card's Vital Signs
Arbiter is monitoring your GPU: Tracking utilization (is it maxed out?), temperature (thermal throttling?), VRAM usage (out of memory stutters?), and clock speeds (boosting properly?). Problems here directly impact your FPS and frame pacing.
🎮 DirectX Crash Forensics Available: GPU crash analysis (TDR events, VRAM exhaustion, present failures, frame drops) requires
--focus-app "application.exe" flag. Run with forensic focus mode to enable DirectX diagnostics (adds 15-30% capture overhead).

⚠️ Clock/power adjusted to load: the driver’s point-in-time snapshot reported an idle p-state (very low clocks/power) that contradicted the measured load and temperature — a common stale read after a driver reset or when the GPU was polled between frames. The values above use the highest-load sample instead. Treat the exact MHz/W as approximate; utilization and temperature are the reliable load signals.
🔴 Max GPU Load
🔴 High Temp
🔧 PCIe Slot Configuration
✅ Load-qualified: the GPU was under load (avg 97%) when this link was read, so a reduced width/gen below is a real finding worth investigating.
Current Configuration
PCIe 4.0 (16.0 GT/s)
x8 lanes
GPU Maximum
PCIe 4.0 (16.0 GT/s)
x16 lanes
⚠️ Configuration Issues Detected:
🎮 REDUCED LANE WIDTH: GPU capable of x16 running at x8 (50% bandwidth loss)
Likely cause: PCIe lane bifurcation (M.2 drives sharing lanes with GPU slot) or installed in secondary x8 slot
Common culprit: M.2 expansion cards in lower PCIe slots can force GPU lane reduction AND speed downclocking
Check BIOS: Look for 'PCIe Bifurcation', 'M.2 Mode', or 'PCIe Lane Distribution' settings
Note: PCIe 4.0 (16.0 GT/s) x8 = ~8 GB/s — still faster than PCIe 3.0 x16 (15.75 GB/s)
🔧 Recommended Actions:
- CHECK M.2 CONFIGURATION: Many motherboards share PCIe lanes between GPU and M.2 slots
- M.2 EXPANSION CARDS: If using M.2 adapter cards in lower PCIe slots, they can cause lane contention AND force entire PCIe bus to downclock
- SOLUTION: Remove M.2 expansion cards from lower PCIe slots, use only motherboard-integrated M.2 slots when possible
- In BIOS, check if M.2_1 or M.2_2 slot is stealing 8 lanes from GPU (look for PCIe Bifurcation settings)
- If GPU is in secondary slot, move to primary PCIe x16 slot (topmost, closest to CPU)
- Performance impact: Minimal for most games at 1080p/1440p, ~5-10% at 4K with high VRAM usage

🔎 DirectX Graphics Activity — Forensic App Focus Enabled
Forensic Mode Active: DirectX Graphics Kernel (DxgKrnl) events captured for frame-level analysis. Shows Present() calls, frame timing, DWM composition, and per-process GPU usage. Enabled when using --focus-app with benchmark/game.
ℹ️ Why the frame numbers differ across panels. Three different counters measure three different things over different time windows, so they are expected to disagree:
• PresentMon frames (17,282) — every present from the whole session (all layers/overlays), used for FPS %, 1% lows and tearing.
• DxgKrnl Present() calls (4,893) — only the focused process’s frame submissions captured by the kernel provider (a narrower window).
• DWM refreshes (934) — desktop compositor vsync events, i.e. how often Windows composited, not how many frames your game rendered.
Tearing is judged from the PresentMon present stream (AllowsTearing flag); a “no tearing” note on the DWM/DxgKrnl side only means the composited desktop path didn’t tear — it does not override the PresentMon tearing figure.
• PresentMon frames (17,282) — every present from the whole session (all layers/overlays), used for FPS %, 1% lows and tearing.
• DxgKrnl Present() calls (4,893) — only the focused process’s frame submissions captured by the kernel provider (a narrower window).
• DWM refreshes (934) — desktop compositor vsync events, i.e. how often Windows composited, not how many frames your game rendered.
Tearing is judged from the PresentMon present stream (AllowsTearing flag); a “no tearing” note on the DWM/DxgKrnl side only means the composited desktop path didn’t tear — it does not override the PresentMon tearing figure.
✅ Gamer Quick Triage (Do These First)
1) FPS shows 0: Present() events were not captured (fix by running as Admin +
2) Stutter / spikes: Close overlays + GPU background apps (Discord/Chrome HW accel/OBS/NVIDIA Overlay).
3) VRAM > 90%: Lower textures first (biggest VRAM win), then resolution; disable RT if enabled.
4) GPU temp > 85°C: Clean dust, improve airflow, set a more aggressive fan curve (throttling = FPS drops).
5) TDR / Present failures: Revert GPU overclocks, verify PSU + PCIe power cables. Advanced / risky: Clean-install driver with DDU only if standard reinstall fails.

● Understanding This Table:
• Present Calls: Frame submissions to GPU - higher = more rendering activity from this process
• Context Switches: GPU scheduling events - high values indicate GPU multitasking between apps
• GPU Share %: Share of total frame submissions (Present calls), i.e. how often each process handed a frame to the GPU — not GPU compute/SM utilization. A high share for your game (e.g. the compositor DWM or System taking a slice) is normal and does not by itself mean those apps are stealing GPU horsepower.

📊 DirectX Performance Analysis & Interpretation
Stable Frame Delivery: 4,893 frames presented with 0.00% failure rate. GPU rendering pipeline operating normally.
High GPU Contention: 32,846 context switches (109/sec) - multiple apps competing for GPU. Background apps (Chrome, Discord, OBS) degrading performance.
Perfect VSync Alignment: 934 refresh events with 0.00% miss rate - frame delivery synchronized to 60Hz.
High VRAM Usage: Peaked at 10,320 MB (84.0%), averaged 10,283 MB. Approaching capacity limit - reduce texture quality or close background apps.
ℹ️ What These Metrics Mean & How To Improve Them:
• Present() Calls: Frames submitted to GPU. More = higher FPS. Low? Check CPU bottleneck or game settings.
• Context Switches: GPU switching between apps. High (>1000)? Close background apps like Chrome, Discord, OBS.
• DMA Buffers: Command queue latency. Slow (>16ms)? Update GPU drivers, check VRAM usage.
• VSync: Monitor refresh sync. Misses? GPU cannot maintain refresh rate - lower graphics settings or enable G-SYNC/FreeSync.
• TDR: GPU driver crash. Any TDR events? Update drivers immediately, check for overheating, remove GPU overclock.
• DWM: Windows desktop compositor. Frame drops? Disable visual effects in Settings → System → Display → Graphics.

🩺 GPU Health & Performance Analysis
Comprehensive diagnostics covering thermal state, VRAM allocation, power delivery, driver stability, and performance optimization.
⚠️ WARNING: GPU temperature at 88°C - thermal throttling imminent (clocks reducing to maintain safe temp)
🛠️ Recommended Actions:
- Thermal Analysis: Current temp 88°C approaching throttle threshold (typically 83-87°C for modern GPUs)
- Maintenance: Clean GPU fans/heatsink with compressed air, verify case has adequate ventilation (2+ intake fans)
- Monitoring: Install HWiNFO64 to log 'GPU Temperature' and 'GPU Clock' during gaming - watch for clock speed drops indicating throttling
Results are workload-dependent and not guaranteed. Validate each change with a fresh capture and keep rollback options (restore point/driver rollback) available.
Technical Note: GPU diagnostics captured via NVML (NVIDIA Management Library) - full power, clock, thermal, PCIe, encoder/decoder, and throttle reason telemetry with ultra-low overhead (~0.05% CPU). Correlate GPU activity with ETW CPU/DPC/Power events to identify graphics-induced system-level anomalies.
