After that it seems to slow more and more down.Yesterday I played it for over an hour and was starting to see the 50FPS mark. I have disabled FPS Smoothing, disabled Dynamic Shadows, DOF, Ambient Occlusion and use only one of my GTX 670's at 1920x1200. So, I've searched the net and found others with the same problem.Īfter I've played the game for an hour or so FPS is slowing more and more down. Now if I could get hold of the older 1.4.1.0 version for Steam to test with. I've recently discovered that my retail version has version 1.4.1.0 of the Borderlands EXE file, while my Steam version has version 1.4.2.1 of the Borderlands EXE file. Update: Turns out it's the Steam version of the game causing low GPU usage and FPS degradation, not the retail version! Retail version has 90 - to almost 100% GPU utilization in-game, higher framerate and no FPS degradation!
