The TLDR of it is: this is expected and there's not much we can do to improve things.
If you find yourself in a situation where a game behaves poorly with D7VK when played above 1080p, and things get worse as you increase the resolution, you're most likely dealing with a game which does DDraw blits directly onto back buffers, and as such hits a slower path which involves additional full image copies to ensure correctness.
Note: The exact resolution where things start behaving poorly may be higher than 1080p at times, and largely depends on memory/PCIe bandwidth and what other things the game is doing to saturate it. It will certainly be under pressure by the additional image copies we have to perform.
The way you can make these things worse in such cases is by:
- using higher resolutions
- enabling or forcing FSAA emulation
So, maybe try not to do that :P. Playing games in their native resolutions and using scaling in your compositor is recommended here.
Pure 3D/draw-using only games are exempt from hitting such paths and will perform well, within reason, at any resolution.
