After recently installing Windows 10, I decided today to play some Pre Sequel. Unfortunately, I seem to be having issues with PhysX on this new OS install.
I noticed that I was getting bad frame rate drops in the game, where I NEVER used to on my previous Windows 7 install. I looked at the in game settings and noticed the the PhysX option was greyed out and could not be changed.
I went to the Nvidia Control Panel (latest driver 355.82) and checked the PhysX settings. The setting was on “Auto Select”, so I tried forcing it onto my GPU (Nvidia 980Ti) but this made no difference. As an experiment, I also tried forcing PhysX onto the CPU but this made no difference either…PhysX was still greyed out in game.
I should mention that the PhysX setting IS available when you first run the game through the Settings tab on the Splash Screen and changing the setting does reflect in the “In Game” value but as soon as you are running the game, the in PhysX setting becomes unavailable…it is visible, but greyed out.
Along with this new phenomenon, the game performance has also been hit severely in places. I seem to be getting bad frame rate drops, even though I have clocked up dozens of hours in this game on my previous Windows 7 install and it was butter smooth. I am ALSO experiencing EXACTLY the same problems in Borderlands 2…identical issues where before there were none.
So, I am having strange problems with PhysX in the Pre Sequel AND Borderlands 2 (cannot change the in game PhysX settings) and I’m getting severe frame rate drops in certain areas on BOTH games.
