I have your exact same hardware. I haven’t G2 but Quest 2. What I can suggest you is to unlock the CPU power from 65W to 130W, in VR make the difference. Of course you can if your motherboard is able to do it from the BIOS, furthermore you need a liquid cooler and not the poor stock cpu fan.
As I see it there is no such thing as best settings. Everyone’s mileage will vary and you need to just focus on one graphic setting at a time until you establish a smooth and visually satisfying flying experience. Plenty of You Tubers out there with great advice to get you started.
I have the G2 with the 3080Ti. I use the NIS API layer for OpenXR set to .80 (80%) with OpenXR set to 100%, and in game Render Scale 100%. I have WMR set to Best Quality so it does NOT auto-scale. I force Motion Reprojection ON in OpenXR. That’s the sweetspot for the G2 right now.
I have same with G2 and 3080ti, but can have openXR 125 atm in certain FPS friendly areas with Motionprojetion forced on. I may try 0,9 NIS APi with 100 OXR. Motion reprojection does need only solid 30fps conficuration, but does it duoble 45 to 90? Would it be best? Or is motionprojection allways tripling from 30 to 90?
I experimented with overscanning, but I think the consensus is that less than 1.0 gives you the FPS boost you need to turn up LOD’s and such. I have not even looked at FPS meters during my testing. I turn down AA and AF to their lowest. Since the background is always a bit fuzzy I can turn down details to get more FPS.
I got a NOCTUA NHD15 and I am not getting any CPU temps above 70 degrees. I really don’t think you need to go to a water cooler myself but that’s just one opinion.
Nowdays there are efficient and cheap water cooler system and for my personal opinion are more elegant and efficient towards air cooler system.
Furthermore, in the air cooler system, the hot air hold inside the case, in the liquid cooler the hot air is pushed outside the case from the fans.
