dureiken Posted February 20, 2023 Share Posted February 20, 2023 Hi drivers, I just reinstalled/formatted my PC with a brand new win 10, and I have a problem that I didn't have before: on my G2, when reprojection is activated (45 or 30 fps), I have waves, distortions on objects. I thought it was coming from BMS: very visible on the kneeboard or MFD, but in fact on the steamVR menu when I force the repro it's the same. Any idea of the cause? When I am at 90/60 fps no problem, once the motion projection is enabled I have those "waves". It disapears when go back to full FPS. Thanks for your help Durei Link to comment Share on other sites More sharing options...
GunSlingerOZ Posted February 21, 2023 Share Posted February 21, 2023 These artefacts are caused by motion reprojection. It doesn't matter which method you use, all forms of motion reprojection have very similar issues. This is why VR games are meant to be played with zero reprojection. Unfortunately DCS is too demanding to be able to run at native frame rate, so we're forced to use reprojection, or be happy with stuttering instead.

jurinko Posted February 21, 2023 Share Posted February 21, 2023 Set the graphics settings to the same as before. MR can handle higher resolution etc., but for the price of more pronounced artifacts/distorsions. Link to comment Share on other sites More sharing options...
edmuss Posted February 21, 2023 Share Posted February 21, 2023 I don't think it's your problem exactly but altering the world scale in openxr toolkit before has caused stepped edges (could be described as waves?) on the sides of the kneeboard before when reprojection is enabled. I'm fairly certain that there is a world scale option in steamvr, might be worth checking it's set to default as it might be causing the same issue. Using the DCS IPD (world scale) setting correctly changes the size of the cockpit around you without causing corruption of the kneeboard edges. The numbers tie up between the DCS setting and the openxr setting - I use 44mm for both (IPD is actually about 63.5) as that gives the best scaling based off my hotas size/MFD position.

dureiken Posted February 21, 2023 Author Share Posted February 21, 2023 Hi, made some tests, it's not only steamVR, same with openXR native and OXRTK motion projection 1 Link to comment Share on other sites More sharing options...

And yes, the artifacts are in both. Edited February 21, 2023 by Glide Link to comment Share on other sites More sharing options...
