Well, if a game is properly optimized for Crossfire, you can often expect to see a performance increase of just under x2. For example, in BF3 on ultra settings using only one Radeon HD 4870 card, I'll usually get an average frame rate of about 40 on Caspian Border. With the second card, however, I'll get an average frame rate of about 65-70. The difference is worth it to me. The problem is that not all games are optimized for Crossfire, and games such as CS:GO and Arma have very poor GPU utilization.I don't understand the big hoolpah with crossfire etc. Christ, you don't even need a graphics card for GO, with a somewhat recent cpu lol
What I meant to imply is that Source/GO are heavily CPU-dependant, not GPU like most other games. Therefore, all of this GPU-bitching ain't gonna fix shit. It's alllll CPU in this platform.Well, if a game is properly optimized for Crossfire, you can often expect to see a performance increase of just under x2.

There was definitely a very mild performance increase with Crossfire enabled before the Arms Deal update. We're only talking about maybe 30-40 extra frames in certain parts of the maps. It wasn't until the Arms Deal update that I realized just how poor the game is at using the second GPU, though. I had always played the game with Crossfire enabled.What I meant to imply is that Source/GO are heavily CPU-dependant, not GPU like most other games.

The update this past Thursday didn't resolve this? All of my frame rate problems are gone now. I guess from a testing perspective it's extremely difficult for Valve to account for all of the potential variables involved (different GPU's and drivers, etc.). Can you describe in more detail the nature of your frame rate drops? Are you getting persistent drops in frames, small drops in frames that come and go, or something else?I've noticed the fps drop as well. Multiple times, I tried jumping into a firefight, and my fps drops to 10. Never had this problem before. Before people go bashing my pc specs, I'm running a i-7 3.2 ghz with 8 gb of ram. While my video card, 460 gtx might be a bit old, its more than enough to run GO flawlessly.
This frame drop also corresponds with massive choke loss, sv and var hitting red.
