I had a spare ATI Radeon HD 4850 laying around and I decided yesterday to finish assembling my new machine with it. Other than that GPU, the rig is all quite modern tech, nothing older than 2 years.
I ran GZDoom on that ATI and was quite pleasantly surprised - no glitches, it ran pretty well. Exceeded 60 FPS in all backends, at least on the vanilla maps. I might out of curiosity try Frozen Time on it - I am not expecting miracles, but it might run better than it previously did with my older machines that it came from.
To be quite fair though - the processor in that thing was a hexacore Ryzen 5 CPU, so I guess I should have expected it to perform better since the CPU was the main deadlock with my previous experiences with ATI cards. Once a scene goes heavy shaders it does start to struggle a bit.
(On that note, if I had known that it would've performed so well on an older ATI card, I probably would have ordered a newer ATI instead of an NVidia)
Anyway ... that just goes to show you how old of a card GZDoom still runs on.

How would a Athlon 200G with Vega 3 stack against current GZDoom, LZDoom and this GZDoom-GLES? Its modern enough to run the whole feature set, but it is low end enough to be beneficial with GLES 2. Performance of Vega 3 is in the GF8x range.

So far i can tell, GZDoom-GLES with its seperate render back end would join an army of low end ports:
- GZDoom 1.8.6 (Heck, Zandronum is still made on this)
- LZDoom
- ZDoom32 (It has a GL2.x renderer)
- ZDoom LE
- ZDoom CL
- and now GZDoom-GLES
Though drfrag is behind most of these.
