Yes, Raceroom only utilizes one thread, so it's quite easy to be bottlenecked by your CPU, and CPU will never show 100% usage.
Even that one core won't be used at 100% as there is some magic going on with CPUs Anyone using OpenComposite - did you stumble across issue that causes the game to crash if you try to switch to other app (Alt-Tabbing)? It reads "Expression is false unexpectedly". I think it started to happening after fresh Windows install and move from Win10 to Win11, but could also start happening a little bit later This is what's in log: Code: 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:136 - Wolf's Open Composite (TIWM fork) version: 1.0.1.0 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:138 - Requested configuration: 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:139 - supersampleRatio=1.300000 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:140 - enableLayers=true 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:141 - enableCubemap=false 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:142 - threePartSubmit=true 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:143 - useViewportStencil=true 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:144 - postInitCmd="" 15:37:16.231 TID:0x1308 TraceStatrtupMsg Line:145 - dx10Mode=true 15:37:33.304 TID:0x1308 VR_InitInternal2 Line:319 - Runtime initialized successfully. 15:37:33.304 TID:0x1308 CVRSystem_012::CVRSystem_012 Line:300 - Created. 15:37:33.304 TID:0x1308 CVRRenderModels_005::CVRRenderModels_005 Line:1076 - Created. 15:37:33.304 TID:0x1308 CVRCompositor_016::CVRCompositor_016 Line:20 - Created. 15:37:37.040 TID:0x1308 CVROverlay_013::CVROverlay_013 Line:602 - Created. 15:37:37.040 TID:0x1308 BaseOverlay::CreateOverlay Line:116 - New texture overlay created "overlay.Menu" "Menu" 15:37:37.040 TID:0x1308 BaseOverlay::CreateOverlay Line:116 - New texture overlay created "overlay.HUD" "HUD" 15:37:39.270 TID:0x1308 BaseCompositor::CreateCompositorAPI Line:362 - Creating new Hybrid DX11 Compositor 15:37:39.271 TID:0x1308 DX11HybridCompositor::Invoke Line:74 - Generating new swap chain 15:37:39.275 TID:0x1308 BaseCompositor::CreateCompositorAPI Line:362 - Creating new Hybrid DX11 Compositor 15:37:39.275 TID:0x1308 DX11HybridCompositor::Invoke Line:74 - Generating new swap chain 15:37:39.283 TID:0x1308 BaseCompositor::CreateCompositorAPI Line:362 - Creating new Hybrid DX11 Compositor for layer use 15:37:39.283 TID:0x1308 DX11HybridCompositor::Invoke Line:74 - Generating new swap chain 15:37:52.152 TID:0x1308 oovr_abort_raw Line:48 - Abort! 15:37:52.152 TID:0x1308 DX11HybridCompositor::Invoke Line:67 - Expression is false unexpectedly Besides that, it works perfectly fine, it's just annoying when I can't check anything outside the game EDIT: Found out what was causing it - NVIDIA G-Sync.
Interesting. Also, and please forgive the dumb question, but OpenComposite still only works with non-WMR headsets in Raceroom, correct? Just want to make sure I didn't miss anything.
Oh, I wrote "one core". It's incorrect, it's "one thread". Because that thread isn't locked to one core by default, Windows can move it between cores. That's why, as Rad said, you won't see 100% usage on one core anyway.
I believe so. The one listed in first post wasn't updated for 3 years and apparently the original Open Composite doesn't work with RaceRoom - at least it's listed as broken in compatibility list
I did some more testing last night, and it seems like I end up dropping down just a few FPS from 90FPS in those sections of Spa you mentioned despite playing with various settings. This seems to happen even if I drop to 4xAA or drop the number of cars rendered. SteamVR resolution doesn't effect it either. Granted, these are primarily GPU related settings that I changed. Is it realistic to expect a locked 90FPS in Raceroom? If so, which setting/s would you suggest changing next? Thanks!
I cant even get R3E too start in VR using SteamVR on my Reverb G2. It just starts to the little Raceroom screen and hangs there for as long as i can wait. Waited 10 minutes today, went got a drink , hung a piss and still that little Raceroom screen is there. What's the trick these days to start R3E?
you have to use your mouse, just click on the screen. btw make sure that raceroom is in the foreground / focus
This is what i have indefinitely. I start Steam, click R3E, set to SteamVR and this is the only screen i get. I click it, it just says R3E isnt responding, close or wait.
It seems i need to use 32 bit SteamVR. It now works. Thanks for you help. But is 32 bit correct or is there another issue not allowing 64 bit to work.
I had same problem and much time spent looking for the cause I discovered it was likely a setting in Pimax software that forced on foveated rendering. Now is working also in 64bit. For info of Pimax users you can turn off parallel projection as well. I tried to get a few different OpenVR/Open Composite mods working to bypass SteamVR in the hope of more fps but seems none of them will work with Raceroom. I tried the older ones that work with AMS2 & rF2. Has anyone found any such mods to get more Frames ?
