Discussion Anyone else use DLDSR on the desktop?
I recently acquired a 5090FE. I have a 4K 240Hz monitor (AW3225QF) and I've been looking forward to using DLDSR to get the 1.78x and 2.25x (5120x2880 and 5760x3240 respectively) resolutions at full 240Hz (which requires the 4K to be driven with DSC, and that my previous GPU a 3080Ti could not do simultaneously). I will refer to these resolutions as 5K and 6K going forward. There is also the full 4x DSR setting providing 8K rendering resolution.
This is pretty great for games where you can gain a lot of extra image quality if you have surplus rendering horsepower. I am even able to run CS2 in 6K and I can hold nearly 240hz by setting it to Medium settings. This really solidifies for me the fact that I can wait for zen 6 before I upgrade my 5800X3D.
In addition, I have also found it to be a comfortable resolution to set on the windows desktop: Everything seems extremely sharp while having the nice there-are-simply-just-no-pixels look you get from MacOS HiDPI resolutions for example. After all I think practically speaking the approach is very similar. A larger resolution is being rendered internally and then downsampled nicely for display.
What I'm impressed by is the fact that I have not seen any prevalent UI elements that are fuzzy due to being designed to be one or two pixels wide and now getting smeared across different distributions of actual pixels, and text looks fantastic. I went to tune ClearType and there is no real discernible difference between options, which I also found interesting, so I am turning it off.
