Tip for squeezing a little more performance out of BF3

1. Go to your BF3 installation folder and find bf3.exe
2. Right click > properties
3. Check the boxes for disable visual themes and disable desktop composition

This will change the color scheme to Windows 7 Basic whenever BF3 starts. This frees up about ~300 MB of GPU VRAM, which BF3 will glady make use of.

I've noticed that CFX scaling has increased a little bit with the extra VRAM.

I simply shifted the textures from Ultra to High, kept the rest at Ultra and the game was very fluid.
In Ultra there is lot of freezing and the fps drops to as bad as 8fps.

This didn't change performance in Ultra, but in High the random 40fps drops for negligible seconds was removed, thanks for this!

Another thing is to shutdown your webbrowser while playing - or make sure there are no flash-thingies (or other heavy web-stuffs) going on in any of your opened tabs.

On my system - quite frequently - gpu/3d performance is going down by almost 50%... I'm forced to shut down Firefox and then disable aero theme in order to get it back to 100%. I can start up Firefox again and re-enable aero theme and it'll stay at 100%. I'm not sure if this is a windows issue, driver issue or an ATI driver issue.

Before starting a game, I always load up Furmark and check if I'm getting 101 fps (@ 720 preset). If I do - then I'll know the game I'm gonna play is gonna run like normal (smooth as silk). If I only get 65'ish fps - then I shut down Firefox and disable aero theme. Then I run Furmark again and make sure its @ 101 fps... If not, re-enable aero theme, disable it again... over and over until I get the right framerate.

So much work when it's acting up like that

Wow, that's a lot of work to make it work.

Right now with Aero and all the usual apps and the browser, my VRAM usage is 117MBs, so that's far from the 300MB gain you're talking about. But still there's something to gain probably

ED: I tried that, but I'm still having extreme rubberbanding. My GPU and CPU both top at about 60% and I have around 40-50FPS (vsync off) so there's something else going on... On the Render.PerfOverlay I have regular hiccups every 2-3 seconds.
