|0003042||Zandronum||[All Projects] Bug||public||2017-03-19 04:52||2017-03-30 21:23|
|Platform||Windows||OS||Win 7 64 bit||OS Version||XP/Vista/7|
|Target Version||Fixed in Version|
|Summary||0003042: OpenGL Hardware acceleration with AMD(Ati) cards results in subpar performance.|
|Description||OpenGL 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 Reproduce||Not 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 It has a newer version of the GZDoom renderer compared to Zandronum 2.1.2.|
|I will try it out later tonight when I get the chance and let you know.|
|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.|
In fact, this is my home machine - AMD @2.0GHz, 4GB RAM, and NVidia as a display adapter (nothing special, passive cooling etc.)
There are Win XP installed instead of Win 7.
I tried to run Zandronum 3.0 with Open GL @max resolution, using "doom.wad" and everything was smooth and fine.
So at least HW is capable enough. If I can help further, just let me know.
|The issue isnt that it's not playable, its that performance is not what it should be for a quad core CPU with such a good video card. OpenGL Renderer lists the R7 but performance is equivalent to the R3 on the APU. I triple checked in CMOS and PCIE is the preference. Theres no way to force disable the onboard, but like I said, it shows that it's using the R7 370 Nitro edition for everything. Map 26 in AV for example has always dogged my P4 rig, THIS pc with win7 64bit does not a single bit better and I dont understand how that could be unless Zandro is somehow not using full acceleration from the R7. If I can provide any further details that may help just tell me what to look for.|
