jerky gameplay (poor frame rate)

I'm going to forward this on to ATI in case it helps, they might not realise I guess - surprised no mods or anything have said they'd forward it on the CO devs tho

I had a read through this thread just now, without knowing I had posted in it. I made mental notes to mention how it's ATi's fault, how they neglect OpenGL, and whatnot.

You can imagine my surprise when I saw my past self saying just that.

You seem to have money to burn, so perhaps you would be better served by buying a new nVidia graphics card. The 4870X2 is indeed one of the fastest cards money can buy, but if you're an avid CoH player, ATi is not your friend. What's worse, even if you COULD disable CrossFire (and I don't think you can), you'd only be using one half of your paid-for graphics card.

I can conjure up some recommendations if you tell me what you're willing to spend, if anything at all.

Do not buy an ATI card.

That's the tl;dr of it.

EDIT: I had a butchers and I think I know how to disable CrossFire. You need to fool Catalyst into thinking CoH will not work with CrossFire on any level. Now, this may be more involved than you'd like, but anything is worth a shot.

You need to make a copy of your CityOfHeroes.exe. Put it in the same directory as the original, rename it to gothic3.exe (if you can't see the .exe at the end, don't worry, it's just hidden). Create a shortcut to gothic3.exe and put -project EUCoH at the end of the Target line. This is important. Get this right, word for word. It should look like:

"C:\...\City of Heroes\gothic3.exe" -project EUCoH

Where "..." is wherever CoH is in. Don't mess with that, just add -project EUCoH at the end.

Now, run the shortcut. All being well your performance should be peachy.

Why could this work? What's gothic 3? Apparently, Catalyst has a list of games within it, and it knows which games like CrossFire and which games don't. ATi being ATi, City of Heroes isn't on the list either way. However, that game called Gothic 3 IS on the list, and it's blacklisted. Catalyst will look at the name gothic3.exe, think "oh eck, no CrossFire for you, mate" and run City of Heroes on half of your graphics card. I got the idea from here.

I did the procedure myself just now, and CoH is running perfectly. My task manager shows gothic3.exe running. But as I don't have CrossFire, I can't tell you if it will help you.
