2 questions about graphics problems

Likely because Nvidia no longer supports AGEIA PhysX. You will need to use a really old driver set, probably from 2007 or 2008, in order for the PhysX card to work.

However, it wouldn't actually give you any benefit. Back in 2005 when CoV launched the Ageia PhysX card did indeed give a performance advantage on single-CPU systems. That was a pretty big deal 6 years ago when most computers sold only had one processing core. That's not such a big deal today where you can get quad-core's for under $100 from AMD.

Turn SLI off and don't run Ultra Mode.

For a list of cards known to work within Ultra Mode, check this sticky post: http://boards.cityofheroes.com/showthread.php?t=251721

You might notice that the Geforce 7000 series is NOT listed. While these cards do support OpenGL 3.x rendering calls, they simply don't have the texture or shader performance to deliver the Ultra-Mode rendering mode.

As far as SLI goes, Nvidia "finally" introduced SLI support for City of Heroes last year. Support for SLI on OpenGL 3.x targets really starts at the Geforce GTX / GTS line though, and as kind of indicated by the GTX 295 card, Nvidia's not too terribly interested in bug-fixing older architectures they aren't selling.

Do you have the old, original PhysX drivers installed? If not, that card's doing nothing save sucking down power.

Since nVidia bought AGEIA a few years back, they changed things. nVidia PhysX isn't quite the same thing as the old PhysX model. And if you don't have the old PhysX drivers installed (and betting the nVidia drivers wipe references from the AGEIA stuff) CoH won't detect it.

And yes, you probably wouldn't have had this problem a year ago. There have been numerous upgrades since then and the graphical engine is a bit heavier than it used to be. Also, if you're on older video card drivers, you may run into problems as well.

Take a look in the "asking for help" link in my sig. Give us the CoH Helper and HijackThis logs. And your cards can take the current 270.61 series drivers. These are what you should be on.

Now SLI isn't going to help you a whole hell of a lot unfortunately. The way the game is coded, it'll help bring up your minimum FPS a little bit, but won't really add to your maximum FPS.

Clicking on the linked image above will take you off the City of Heroes site. However, the guides will be linked back here.
