So, as the title says, I feel my FPS decline signifantly after every game update. While my hardware is the same for 6 months now, and my useroptions.ini hasnt changed in the same timespan, my framerate declines after every update. This has gotten to a point, where I get 60 FPS in bigger fight, than the 85 I once used to. This causes more input lag and really sets me off. I heard of other people reporting similar things. Maybe the devs could look into it and identify the reason.
Interesting you mention this... this afternoon, our FX artist just identified and made a change that resulted in a 20-40+ FPS increase when shielded and ADS for most weapons used by Heavy Assaults. It's in testing now and we plan to publish it via a client-only hotfix (no downtime), sometime tomorrow morning/mid-day.
I know it doesn't address all of the FPS issues mentioned here, but just wanted to let you know that we continue to chip away and these types of improvements.
