Ski01 Posted June 10, 2024 Posted June 10, 2024 Hi, I have an i5 and 3080 and G2 - tweaking VR settings. I running VR using WMR with G2 at 60hz, no reprojection. I'm getting 60 frames most of the time and the FPS display is saying "CPU" bound in the display and never going above 60 What does CPU bound mean in this context I would have assumed that if the display is self limiting the 3080 output to the G2 at 60Hz (which would then sound a bit like vsync for 2d) - then I wouldn't think this is a "CPU" limitation?? Any advice most appreciated.

If it's red, you need a faster cpu SYSTEM SPECS: Hardware AMD 9800X3D, 64Gb RAM, 4090 FE, Virpil T50CM3 Throttle, WinWIng Orion 2 & F-16EX + MFG Crosswinds V2, Varjo Aero SOFTWARE: Microsoft Windows 11, VoiceAttack & VAICOM PRO YOUTUBE CHANNEL: @speed-of-heat

When you see "CPU Bound" in the DCS FPS counter it can be missleading and not necessarely mean your CPU is not keeping up. You need to use OXRTK FPS counter and see what is the reported frametime for your GPU and CPU. If the frame time exceed 16.67ms then the system component (CPU or GPU) exceeding this value is limiting factor, or the bottleneck in your system. At that point you have two options: Upgrade Hardware or Lower Settings. If any of the two components seldomly exceed the 16.67 threshold, then you are in a good place. If you are using the single thread version of DCS, then you could experience CPU bottleneck more easily. Better to use Multi-Thread to split the load on the CPU between several cores. 1 ------------------------------------------------------------------------------------------------------------------------------------------------------------ 9800X3D, RTX 4090, 96GB DDR 5, MSI Tomahawk 870E, Crucial 2TB x 2, TM WARTHOG COMBO + PENDULAR RUDDER PEDALS, THE AMAZING PIMAX 8K X, Sony 5.1 Spks+SubW | DCS, A-10C_II, AH-64D, F-14/15E/16/18, F-86F, AV-8B, M-2000C, SA342, Huey, Spitfire, FC3.
Ski01 Posted June 11, 2024 Author Posted June 11, 2024 Thanks Wipeout - I believe the standard ‘version’ of 2.9 is MT - or do I still need to go to the MT folder?
WipeUout Posted June 11, 2024 Posted June 11, 2024 Since DCS 2.9.3 there is only the "stable" version, there are no Open Beta version updated anymore. The MT version is in the bin-mt folder yes. In any case, it is better to use the latest version of DCS which is 2.9.5.5518 now. As for WMR and the G2 and how to use OpenXR as your runtine (required to use MT), I don't have much knowledge about this as I am a Pimax guy... ------------------------------------------------------------------------------------------------------------------------------------------------------------ 9800X3D, RTX 4090, 96GB DDR 5, MSI Tomahawk 870E, Crucial 2TB x 2, TM WARTHOG COMBO + PENDULAR RUDDER PEDALS, THE AMAZING PIMAX 8K X, Sony 5.1 Spks+SubW | DCS, A-10C_II, AH-64D, F-14/15E/16/18, F-86F, AV-8B, M-2000C, SA342, Huey, Spitfire, FC3.
Digitalvole Posted June 13, 2024 Posted June 13, 2024 (edited) I was going to start a new thread, but do you mind if i quickly hijack this one for a cpu based question? when using then oxrtk frame time counter (and I’m using quad view DFR) there are 2 cpu frame times, app and rdr I think but I can’t properly remember. What is the difference, and do you add the 2 together to get your total cpu frame time? Sorry, didn’t see that other thread, I’m a numpty Edited June 13, 2024 by Digitalvole
