So probably from now on, they will not allow any form of downsampling at all. This has 100% made me decide to not get AMD the next time I upgrade.
They are really messing things up...
I found a way to make 2880x2160p possible with amdgui on 7xxx cards. max was 2720x1530. Even tho 2880x2160p is not 16:9, when scaled to full screen it proportions come out right. Just as screenshots I've been posting. most gtaIV screenshots I posted couple of pages back were made at 2880x2160p on 7870, win7x64 bit and 13.6b2 drivers. it is convoluted and weird, but I was also able to make 4k resolution set in amdgui, not bsod and crash pc. Barely anything can be seen with this setting, but at least it can be done not to crash the pc. It captures well on screenshots, tho they have to be captured almost blindly, because in realtime, it is messed up.
edit: yeah, I know I've pm'd You all of this already Derko1, but wanted to post an answer here too, for heads up
I could post instructions if someone would like em, but I don't think it is worth all of the weird solutions just to get some lines more than 2720x1530...Edited by HiCZoK - 7/23/13 at 10:36pm
