So I play and edit my game with a 4K monitor, but that lowers my performance so I rely on screen percentage to render the game at a lower resolution.
The problem I have is that the antialiasing that I use (TAA) is applied after the game upscales the 50% screen percentage to my 4K monitor, which does not look as good as it would on native resolution (100%)
How can I make the antialiasing take effect before the game scales the 1080p render to 4K?
well hello there. i’m kinda certain that is not the case. either way… you have options to use tsr and/or dlss in case you have an rtx card. should improve image quality by a good amount.
I have a 4k TV for my display but same issue. I edit in 4k, and play at 2560x1440 w/4k diffuse textures (2k normal/AO, 1k rough/gloss/displace).
I can’t tell the difference between native 4k resolution and the above. Even with using 1k textures across the board, I have to to look for it, lean IN and I’m literally ~20 inches away from these words I’m typing. If I sit the comfortable-distance back I play games at I cannot readily tell at all.
You’re talking about going from ~2.1megapixels to ~8.3. Temporal-sampling is GOOD but not quite that good. Maybe on game with very sharp corners with blocks, like a demo level, but once you get into odd, organic shapes, the costs are much higher.
I can suggest the newer TSR is more performant and more viable vs TAA. As noted. DLSS is an option, and in my experience a just-better-results vs either of the previous two options, but also generally more performant by a decent degree. Even just turning it on gives better de-noising across temporal-samples but also seems to give a passive performance boost even at screenpercentage=100…
If you make your original resolution too small, there is simply not enough history accumulating in the history-buffer; you WILL get ghosting to some degree. You’ll likely be able to convincingly upsample, but in motion it’s going to show.
More specifically to your question, the temporal-sampling technique IS the anti-aliasing b/c what it does for you is really the opposite of what anti-aliasing traditionally is. AA is an attempt to recover lost information, smoothing out an image. TSR/TAA is generating content from a smaller image, filling in the gaps.
