We've all done our own .ini tweaks for performance, but I think I've really hit the nail on the head with the .ini on my rig by delving into some stuff that doesn't seem to be thought of/agreed upon yet. What I did was:


bEnableBoundingVolumeOcclusion=1
bUseObliqueFrustumCulling=1 (I had to add this line)

These seem to impact my performance in a positive way. I don't know why but maybe you should try it too.

I have all the "Threaded" lines set to 1.
I used to have all the "Background" load lines set to 1 too, but I just recently discovered that turning these back to 0 really helps game stability in terms of random crashing.

With iPreloadSizeLimit... well, I have 8 gigs of ram and still had stability issues, but when I allocated a full 157286400 (I think thats about 6 gigs?) it helped stuttering a lot, but may have increased loading times slightly. Worth the change.

See if this works for you.
