Mostly directing this question @ AMD.
I have been trying VSR since it came out with my Dell U2711 2560x1440 display with 290X. I tried it with Dota 2 and set the Max available resolution which was 1800p. Problem was for some reason the game look much worse than native 1440p. It looked very blurry. This was pre Crimson drivers.
Yesterday I tested it with a very old TN Samsung 2253BW 1680x1050. I set VSR to 2560x1600. I then played Dota 2 and IQ was so much better.
What can the problem be?
Is it IPS technology problem?
Is it 1440p>1800p problem?
Is it the internal monitor scalar problem?
Was it something fixed with Crimson? (Don't have 1440p to test anymore)
before I went native 4k I ran 1440 myself "asus pb278q" and noticed some game would be blurry if both vsr and aa was used , drop one or the other and it fixed the issue
