player_0 The latency issue is Windows(M$) related as far as I remember openGL was running 10-20ms slower compared to Direct3D9 at the same fps, I think Higor said limiting fps helps this though but not sure by how much though. The guy that is making a Vulkan driver for UT99 has used a method that involves DirectX11 to then run a Vulkan window to get around the stupid Windows issue with latency, I think there was some talk of doing something similar with OpenGl but I might be wrong.
From what I've seen the AMD drivers are just not to the same quality as Nvidia and have some issues going by what I've seen said by AnthraX joking about it a few times. I can't comment as I only used an AMD card for a few days until selling it in a computer as it only had single link DVI meaning I couldn't run at 144hz, it didn't have a displayport, and this monitor can only do 85hz via HDMI so I went back to a GT710 for a while... that could do 144hz even if it struggled to maintain 144fps in UT.
