thanks for the guide, after messing about with vrperfkit manually by myself i decided to try out this guide anyway. for context, i'm on a Rift S and i'm running VaM in oculus mode instead of OpenVR, so SteamVR doesn't hog resources.
in this configuration, it doesn't seem like the foveated plugin has any effect on the game, which i confirmed by enabling debug mode and still not seeing any change. the vrperfkit does work though. i went along with the recommendation and only left FFR enabled, upscaling disabled.
the method of enabling NIS in control panel doesn't seem to have any effect. makes sense, considering how the linked article says at the very end that this setting is not compatible with VR. so if this ever actually worked for Blaspheratus, that's very interesting.
so because of that i changed my mind about upscaling via vrperfkit, and enabled it back on - but for some reason that's very unstable for me, most launch attempts cause not only my VaM, but my oculus software to just crash completely. i played with different upscaling methods and other settings, and i thought leaving the method at "CAS" is the solution, but eventually it just started crashing again completely unprompted :|
however, asynchronous spacewarp... what problem is that feature supposed to solve again? because disabling it was exactly what i needed for some of the scenes where i can't get 80 fps and i had to settle for 40, but without ASW the same scene is now 60-65. much better.
that leaves upscaling with the Lossless Scaling app, i'll give it a shot later. although the biggest drawback from reducing render scale is the UI (the more distant the panel, the worse) and hair, starting to shimmer like crazy. who knows, maybe this app will surprise me.
oh and i'll have to do some symbolic link fuckery with the shader cache before increasing its size, since i don't really have much free space on my system drive...
