Based on the article you posted, it looks like this is something that Pimax could add to their existing FFR. Basically, I think that they’d need more choices (beyond Conservative, Balanced, and Aggressive) and tweak their existing code.
It would be awesome if Pimax could do that. It would really help Elite D, which suffers badly from aliasing.
@Sean.Huang, please have someone investigate this (at an appropriate time), for future FFR improvements. Thanks!
The new driver also has per-game max framerate setting, so you can set your target framerate below refresh rate, set a PiTool/SteamVR supersampling that reach that target for sure, and VRSS will use any free headroom to make MSAA area as large as possible
You need to set MSAA in game before, VRSS is operating on top of MSAA
Absolutely! My suggestion was a way to make the feature readily detectable, not as a setting for normal use.
I think the most interesting preset (as described in the link by drowhunter) is a “Balanced” mode where the central area is 4x SS, the intermediate area is 1x1 (1.0 SS), and the outer area is 2x2 “coarse shading” (0.5 SS). That would provide a noticeable visual quality improvement to the central area, with a faster framerate than if the entire image was rendered normally (1.0 SS). That would be especially useful for Elite D, which suffers from aliasing artifacts.
Unfortunately some other article appeared to be singling out the feature only being applicable to forward renderers, which would presumably rule out Elite.
…on the other hand: I seem to recall you have mentioned FFR having an effect on the game for you, albeit a somewhat erratic one?
I don’t think forward rendering is required. From what I’ve read this appears to be a form of supersampling (of tiny little tiles). FFR fine works in Elite D. There’s an issue with excessive shimmering around the edges of the screen, which mostly affects orbit lines. The 2 most recent versions of PiTool have reduced the shimmering area somewhat (at least for Conservative mode).
I’ve actually been using FFR lately, which really improves the framerate. Once I have a 3080Ti (or whatever), I would like to use the High (4xSS,2xSS,1x) or Highest Quality (8xSS, 4xSS, 2xSS) shading preset to drastically reduce the aliasing in ED.
(EDIT: Maybe it could be worth having a bit of a vignette applied specifically to the orbit lines layer, fading them out in the low resolution periphery… Or having the driver (optionally!) progressively blur/TAA/“intelligently”-reconstruct the entire far periphery somewhat, to dampen the pixels that blink on and off…)
Sure, blending would help. Or you could turn off orbit lines, but I think High Quality (4x,2x,1x) would suffice. The next generation of xx80 GPUs will probably be able to do that at a reasonable framerate.
From what I read the original VRS only affects the pixel shaders and in one way only (degrading).
The new VRSS should affect the render path right from the start, i.e. including the geometry. Whether it improves the textures in the game however is another question, answer of which may depend on the game itself (@MReis).
MSAA is not SSAA (those we call Supersampling in VR), even it’s similar
So to get benefit from VRSS, I guess, you need to lower SS (SteamVR SS), rise in game MSAA, and activate VRSS, in order to get the same visual quality with higher framerate, or better visual quality at the same framerate
oh so you’re saying detecting it visually might not be as blatantly obvious as pimaxes FFR. where you van literally see circular steps of quality reduction.
If you are interested to try it with other games, you can enable the option for a particular game with Nvidia Profile Inspector -> Show unknown settings from NVIDIA predefined profiles -> 0x00D5E9C6 set to 0x00000001.
The 0x00D5E9C7 is for the value (0x00000001: always, 0x00000002: adaptive).
(the game need to support MSAA)
