Codemasters and 2d Surround - Major Problems

post #1 of 7
Thread Starter 

Hey OCN,

I've got Dirt 2, F1 2010, and GRID having some serious problems with 2d surround. They run fine on one monitor, however, setting them up with a multi monitor resolution (5760x1200) makes them completely unplayable. These games all have the same developer in common, and I don't know why I can't get them to run fine when I see tons of youtube videos of people running these games flawlessly...

Also, I'm able to run BFBC2, Hawx 2, NFS, Dead Space and Call of Duty MW2/Blackops at 5760x1200 so this can't be a hardware issue

I made a video to show you guys what the issue is.

Reduce AA, or lower the textures.

Even tho two 470s are nice, they still have less memory and power to what you require from them.

Some games just require more than others, even games from the same company.

I agree. Methos07 your expecting too much.
F1 is one those games you need as much vram as possible.

I play those games on tri sli 480's. The guys are right you may be running out of ram. If you use MSI afterburner you can check how much ram is being used. If you find you are very close to the amount of ram the 470's have, you will need to start reducing quality settings to make it playable.

I lowered the AA to nothing and I use 1035mb on each card while racing in F1. I was able to get Grid to start before obviously but now it just crashes when I open the game. Seems like AA was the problem. I just waterblocked these 470's and they are running 850mhz core clock, sucks that vram ends up being my Achilles heel.

Take a look at the graph below (GTX460 SLI 1GB vs 2GB for Dirt 2)

At your 5760x1200, Dirt 2 will use ~1.1GB Vram at 0xAA and ~1.3GB at 4xAA. So, given your GTX470 has 1280MB Vram, it is better to use 0xAA or 2xAA and, as suggested in the review article, turning off/down Post Processing should help too.

Do not feel too bad because even if you use a 2GB per core card, it will still be all used up if you set AA to 8x. (Perhaps Gainward's 3GB version of GTX580 is the cure?)

Thanks for the reply, that was pretty informative. I was just figuring if I could run BFBC2 at max everything on three screens, grid would be NP. At least my high resolution makes AA pretty unnoticeable after a certain point.
