I’ve noticed this in a few scenes now. I can’t tell if its just the pimax or the game, but when jumping off of balconies and such, it feels suuper slow motion too, like moon gravity almost. Makes me feel like something isn’t working right with physics timing or animation timing, who knows.

A weird note, I get the bad auto pixelation if i play in 90 Hz along with a message saying the settings are too high. Switching to 120 Hz, which nearly has the same fov for me as normal at 90 hz, I sometimes don’t get that warning, and more importantly the resolution doesn’t seem to auto correct, or at least nearly as harshly. 120 Hz it is for me then, because it looks phenomenal in high res!

“setting.r_texture_stream_max_resolution” sounds very much like a limiter on how large texture mipmaps the game is allowed to move into VRAM (from elsewhere, producing bus traffic, and possibly latency), during gameplay. Nothing to to with the render resolution, if that is the case (other than that when rendering at higher resolution, the game will see more use for larger mipmaps).

Dynamic resolution scaling should constantly adapt, to give you the highest possible resolution that still meets the refresh rate - this includes increasing the render resolution, from the requested “base” render target size, if headroom becomes available for it any time during play – not just degrading.

So reducing the refresh rate (or lowering game graphics quality settings), should definitely make the dynamic quality reduction less likely to kick in.

If one find it working better with 120Hz than 90, I have to ask myself whether that is really full 120Hz compared to real 90Hz, or if the former is not 60fps with any form of forced frame synthesis filling in the blanks…

If a 2080 seems to struggle: There are no other bottlenecks, are there? What does the frame time graph show for CPU, and not just GPU? Does the BIOS RAM speed setting match the capabilities of one’s RAM sticks?

So 120hz for me, is hard to describe. Its like every second the whole image kind of glitches and doubles and then goes back to normal.

So I was having the dynamic pixelation problems in game, but it seems 1 of two things fixed it and I’ve not seen it since. Either a) FFR to close, or (I’m guessing) b) turn off Smart Smoothing in Pitool.

I’m guessing the latter would likely confuse steamvr, as it’ll detect that the framerate has dropped to half, and try and fix that with the resolution (as it can’t use it’s own motion smoothing), causing the horrible pixelation. Now that I turned that off, have settings on Ultra with my 2080ti and I get occasional frame drops from 90hz, but everything is running well, and no pixelation. Although I do notice my GPU isn’t being fully utilised. I haven’t played with the slider yet, as the one time I put it up to 4.5, I kept getting a black flicker in my right eye

Hi, is there any fix to the blood glitch? Bloods are not align between left and right eye.

yep
