GTX 680, Performance Expectations

[strukt]

Hi there

I was wondering what kind of performance I should expect from the GeForce GTX 680? The machine boots and works all right, its based on this motherboard: ASUS P8Z77-I with i5-3570k, 8GB RAM. and the graphics card is a ZOTAC reference card.

In games (WoW, StarCraft2) I experience some stuttering, not really sure why. It stutters, then goes smoothly for a few seconds, then stutters again. It is almost feels like HD lag but I run the games from SSDs and TRIM is activated according to system information.

Any ideas?

No one have any ideas? The performance is actually okay, but it stutters.

Ok I think I found the solution to my problem. Deleting the AppleGraphicsPowerManagement.kext gave a huge performance boost. The stuttering is almost gone!

I've noticed that same thing on my box as well in SC2. My FPS are acceptable and playable, but not exactly outstanding. Valve games seem to run without a problem and I haven't tried playing Diablo III yet. I did some quick poking around a couple weeks ago and it looked like it was mostly a Blizzard related issue. I guess they just aren't as optimized on a Mac as they are on Windows, or at least that is what i've heard. From what I've seen it makes sense. I had the exact same specs as below on my Windows box except I had a Radeon 6970 instead of a GTX 680 and I got a constant 60 FPS, it wouldn't even ever dip below 59FPS (v-sync turned on), even on the unit preloader map. Now I seem to get a steady 30 - 40 FPS in game and about 8 - 10 FPS on the unit preloader map. I'll try deleting the .kext and see if that helps.
