Flyboy Posted Monday at 10:48 PM Report Posted Monday at 10:48 PM Was having a lot of issues lately with my performance so I did some checking using Claude AI and it came up with this, which I used and it seems to be working a lot better so far. I also attached the pdf version of this. DCS VR Performance Optimization Guide For High-End Systems with Pimax VR 1. ParkControl Setup (Fix Core Parking) Download ParkControl from https://bitsum.com/parkcontrol/ Install and open ParkControl Go to Settings → Experimental Enable "Always Show Bitsum Highest Performance" Return to main screen Select "Bitsum Highest Performance" from the power plan dropdown Verify it shows 32/32 cores (or your full core count) with Parking: Off 100% 2. Process Lasso Setup (CPU Priority Management) Download Process Lasso from https://bitsum.com/processlasso/ Install and open Process Lasso Set the following process priorities: Process CPU Priority I/O Priority DCS.exe High High PiService.exe Above Normal Normal pi_server.exe Above Normal Normal Moza (FFB software) Above Normal Normal PiPlayService.exe Normal Normal Right-click each process → Set Priority → Choose level Select "Always" to make it persistent 3. NVIDIA Control Panel Open NVIDIA Control Panel Go to Manage 3D Settings → Program Settings Add DCS.exe if not listed Set these options: Power Management Mode: Prefer Maximum Performance Low Latency Mode: Ultra Threaded Optimization: On Optionally add Pimax runtime processes with same Power Management setting 4. OpenXR Toolkit Settings Setting Value Upscaling Off (use DCS DLSS instead) Override Resolution Off Fixed Foveated Rendering Medium Turbo Mode On Motion Reprojection Auto Frame Rate Throttling Off FOV Override Off Note: Don't stack upscalers. Use either DCS DLSS or OpenXR NIS/FSR, not both. 5. DCS Graphics Settings Setting Value Textures High Terrain Textures High Visibility Range Medium Heat Blur Off Shadows Default Secondary Shadows Off Water High MSAA Off DLSS Quality or Balanced Depth of Field Off Lens Effects Off Motion Blur Off SSAO Off SSLR Off Clutter/Grass 1000 Trees Visibility High Preload Radius 150000+ Chimney Smoke 0 Anisotropic Filtering 16x VR Tab: Pixel Density: 1.0 Bloom: Off 6. Pimax Software Control FOV through Pimax Play/PiTool (Normal/Large), not OpenXR Toolkit Set refresh rate based on what your system can maintain (90Hz recommended) Let Pimax handle resolution natively Key Principles Core Parking - Intel hybrid CPUs (12th-14th gen) park E-cores by default, hurting DCS Single Upscaler - Use DLSS in DCS OR NIS in OpenXR Toolkit, never both DCS is CPU-bound - Many stutters are main thread, not GPU FFR is free performance - Pimax wide FOV makes peripheral quality loss invisible Restart after changes - Especially after ParkControl and Process Lasso setup Troubleshooting Still stuttering? Lower Visibility Range to Low, Shadows to Flat Blurry image? Increase DLSS to Quality, or switch to OpenXR NIS at 85% Terrain pop-in? Increase Preload Radius Low GPU usage? CPU bottleneck - normal for DCS, priority settings help OpenXR Toolkit Settings Category Setting Value Upscaling Mode Off (using DCS DLSS) Alternative NIS at 80%, Sharpness 75% Image Adjustments Override Resolution Off Resolution Per Eye Off FOV Override Off Performance Fixed Foveated Rendering Medium FFR Pattern Ring Turbo Mode On Motion Motion Reprojection Auto Frame Rate Throttling Off Misc World Scale 100% (default) Post-Processing Off Pimax Play Settings Category Setting Value Display Refresh Rate 90Hz Field of View Normal (or Large if stable) Resolution Native (don't downsample) Render Quality 1.0 Smoothing Smart Smoothing Off (let OpenXR handle it) Compulsive Smoothing Off Compatibility Compatible with Parallel Projection Off (unless needed for specific game) Hidden Area Mask On Backlight Backlight 80-100% (preference) Runtime OpenXR Runtime Set Pimax as default OpenXR runtime Important Notes Refresh Rate: 90Hz is the sweet spot for DCS - achievable on high-end hardware 72Hz if struggling to maintain 90 (smoother than missing frames at 90) Don't use 120Hz for DCS - too demanding FOV Options: Normal - Best performance/quality balance Large - More immersion, ~10-15% performance hit Potato - Only if desperate for FPS Smart Smoothing vs OpenXR Motion Reprojection: Use one, not both OpenXR Toolkit's Motion Reprojection generally works better Turn off Pimax's Smart Smoothing when using OpenXR Toolkit Parallel Projection: Leave Off for DCS (not needed) Only enable for games with broken stereo rendering Hidden Area Mask: Keep On - gives free performance by not rendering pixels you can't see Quick Reference Pimax Play: 90Hz / Normal FOV / Render 1.0 / Smart Smoothing Off / HAM On OpenXR Toolkit: Upscaling Off / FFR Medium / Turbo On / Motion Repro Auto Hardware tested: Intel i9-14900HX, RTX 40 series, 64GB RAM, Pimax VR DCS VR Performance Optimization Guide.pdf Klaiber 1 Quote
