I've got 2 questions about how my new card is performing in games.
1. I tested 8X MSAA vs. 4X SSAA performance in Mass Effect 1&2 and Portal 1&2. I forced AA through the driver for each... For some reason I'm getting higher fps when using supersampling than multisampling. Granted, I'm taking twice the samples in MSAA, but according to Tom's Antialiasing article I should be getting twice the framerate with 8X MSAA!
Example: I pop two portals beside each other in a wall, and my framerate dips to 45 with 8X MSAA - I switch to 4X SSAA and the same scene gives me 57 fps. Also walking around the Citadel in ME1 I get about 40 fps with 4X SSAA and a little over 30 with 8X MSAA. I'm fine with it, because supersampling looks way better, but I wish I knew the cause.
I know draw distance is CPU-dependent, but is MSAA, too? (I know mine is rather weak, but it's still able to play these games well.) SSAA always destroyed my framerate with my old HD 5670 512MB, but 8X MSAA was just as playable in these games as with my new HD 6870.
2. My second question is a quick one: Why is GRID maxing out my GPU? Every time I look at Afterburner, the GPU usage shows about 90-100% while racing or showing a replay. My card gets pretty hot too. I have all the settings cranked up with 8X MSAA, but Crysis 1&2 on Very High are less intense...
Thanks for the help!
