Thanks Dege, for checking out my pointers!
Yeah, that's what I thought the deal would be with games with that kind of shader problems. And why I have emulators as an example in my mind, maybe in future it'd be possible to implement some kind of per game shader upscale offset tweak like some emus do? Cause ofc it's obvious there couldn't be an universal solution.
About all other games I recheck my settings, I guess there maybe something wrong somewhere on my side.
Btw, I have a kinda esoteric question also. I decided to test Conquest Frontier Wars for a change and apparently it supports 4k natively, but ui text starts to break up slightly at high resolutions, so I dialed down to 1080 so then to upscale to 4k through dgvoodoo. It worked without problems, but I almost immediately noticed that quality is not really similar, 4k through dgvoodoo looks noticeably blurrier.
There was msaa applied in those screenshots, without it blurriness is still present, maybe not that apparent.
And it shows this way not only in this game, but in most I tested, maybe in all of them. I tried to experiment with settings, to change resampling to point sampling or bicubic, but it didn't give me much difference. 1080 should be integer to 4k and give super crisp results at all times, if I understand everything correctly? It's an expected behavior or I could try something else somewhere?
