Alt+Tab temporarily fixes low fps | Forums

[bagpuss88]

No matter what level of graphics I use (right from minimum up to 1680x1080 4xAA, 4xAF with all settings turned on, except Vsync), I experience major slowdown in FPS periodically in the game. It tends to happen went entering a large new area.

I have found that this can always be fixed by Alt+Tabbing out of the game and straight back in. Just waiting in-game for the fps to rise again doesn't work!

Anyone any ideas what might be causing this?

I've had this problem in other games, it's usually caused by what's known as a "memory leak," where due to poor coding the game starts to eat up more and more RAM until your system runs out and the game starts to chug. Alt-tabbing resets the process, so you get your FPS back, but it's a pain. Same thing happened to me in Far Cry 2. Anyway, this is the kind of thing that can only be fixed via a patch, and seeing as most people can't get the patch that's supposedly already out there, I wouldn't get your hopes up.

I honestly doubt a patch was ever released. Only Libini1989, or whatever his name was, reported it. I haven't seen anyone else, anywhere, claim to have received the update.

It seems to be doing the opposite for me. When I alt-tab the game comes back with worse frames. Takes about a minute then it's back to normal.

I've found the solution!

In NVIDIA Control Panel, uncheck the Enable Stereoscopic 3D box. That solved the problem for me, and I think overall FPS are up as well as not dropping substantially periodically.

NOTE: I was not using 3D effects - they were turned off. My solution is to stop 3D being on standby in the game.

ALT tab does not work for me?

[bagpuss88]

When you say ALT+tab doesn't work for you, do you mean it doesn't solve the slowdown, or you can't taskswitch out of the game?

If the latter, perhaps try Ctrl+Alt+Delete to get the task manager options up, then try going back into the game.

Alternatively, just try disabling 3D as I described above to see if you can solve it!
