Summary0003042: OpenGL Hardware acceleration with AMD(Ati) cards results in subpar performance.
DescriptionOpenGL with this system which is an [AMD quad core @ 2.05 ghz 8 gigs ram, AMD R7 370 Nitro Edition 4gig vram pci 3x @2x] is equal to if not worse than the performace I got on my single core Pentium 4 system running a 256 meg graphics card on AGP. Performance is only slightly better than software acceleration by 0000012:0000020 fps across the board topping out at 200 when there's no monsters on screen. In moderate or heavy monsters it drops down to 20-30 fps. I'm not even talking chillax heavy, any map with 30+ monsters in a group causes framerate slowdown.

This system runs Warframe seamlessly at almost max settings, League of Legends at max settings, Rift at max settings, pretty much everything except Zandronum. I understand this system isn't fantastic but it's head and shoulders better than my P4 rig, why is the performance so bad?
Steps To ReproduceNot really sure aside that I'm told this is an inherent problem with not properly supporting AMD(ATI) graphics cards.

Is the performance in 3.0 any better for you? It has a newer version of the GZDoom renderer compared to Zandronum 2.1.2.

It doesn't seem to make any difference which version I use it still looks no faster than software, almost like nothing is hardware accelerated even when opengl is selected.
