As I’m learning more about things I’ve run into an issue which I don’t know how to resolve (or if there is a way to resolve it). When I push high-resolutions through my 5K+, for example using the PiTool Rendering Quality at above 1 in a native VR title (Skyrim VR), or when using Vorpx and pushing high game resolutions (FO4 at 4K), I’ll get momentary glitching and hiccups and some extremely strange behavior even when my FPS is absolutely fine. Looking at fpsVR I can see some extreme spikes combined with very low GPU / CPU usage. Once things “steady up” I can usually play just fine (depends on the situation). Looking at that same situation in Vorpx I see that the game might be rendering just fine, but that the HMD FPS has dropped to something like 2 (Vorpx lets you see what FPS the game is rendering at, and what FPS is being sent to the HMD). There appears to be little or no relationship between resources used whether or not this happens, at least in terms of game FPS. For example, using Brainwarp I can set the PiTool quality to 2 and still easily render Skyrim VR at 45fps with no trouble. But doing so will result in aforementioned glitches. FO3 I can run at 4k with zero problems, but FO4, even with Z-buffer 3D (and thus quite high FPS with low 3D overhead) it will glitch. So it’s native VR titles, as well as non-native titles through Vorpx, with slight, if any, relationship between how much CPU/GPU I’m actually using, but a clear relationship when it comes to resolution settings.
Any tips? Thanks!
