Street Fighter 4 FPS slowdown in Crimson Viper Stage

[Golgatha]

So I'm running along at 60FPS on Street Fighter 4 and I get to the Crimson Viper level. My FPS drop to 31-42 and the game becomes unplayable or at least less enjoyable. This is typically the 3rd fight and the first 2 are flawless at 60FPS. Sometimes an alt-tab will fix the issue. I can pull 200 FPS or so when V-sync is disabled on the in-game benchmark, so I don't think the game is bogging down.

Don't know what to do and Google is no help. Anyone else having this issue or anything similar?

If I can't get some resolution to this problem, that's $20 down the drain since I purchased it on Steam for something different to do at LAN parties. I have the PS3 and XBox 360 version of this game too. Had the PS3 first, then bought a 360 and wanted to play Online with my bro-in-law ($19.99 Gamestop deal awhile back FTW), and now I bought the PC version for LAN parties. Capcom owes me some support on this one damnit!!

Probaly something to do with crossfire or drivers. I just have one gtx 280 and I never get slowdowns. If you see me on sf4 I'd be happy to kick yo ass. Shane476 username

Try updating your graphics and sound drivers.

This was a good suggestion. I played a game all the way through without slowdowns by unchecking Crossfire in the CCC software. I enabled Crossfire in the CCC, but disabled parallel rendering in the PC settings and I get the slowdown in the Crimson Viper stage again. I will try to repeat the success of disabling Crossfire in the CCC software and then report the bug to ATI and Capcom.

Even on a single 4870, the game runs at highest settings with 1680x1050 resolution with ease.

The parallel rendering option is for cpus, not gpus, I think. It should be called multicore or multithreaded rendering.

Ah, that makes sense as you shouldn't really need an in-game option for Crossfire X. Either it has a profile in CCC or it doesn't.

Ok, I'll try enabling parallel rendering but disabling Crossfire X in CC again and see how that works out.

Well, I played through 3 characters, which included a couple of trips to the Crimson Viper stage, with no slowdowns after disabling Crossfire in the CCC. Parallel rendering seemed to have no effect on framerates. Game ran fine with parallel rendering turned on or off as long as Crossfire was disabled via CCC.

It's increcible how all game forum users aways have an "ultra hi-end PC" like a "Core i7 920@3.2Ghz | Crucial C300 256GB SSD, 2x 300GB Velociraptors in RAID 0 | 12GB DDR3 RAM | 2x HD 5850 in Crossfire | 910w PC Power & Cooling Silencer PSU" , but anyway, don't got to run SF4 in the maximum.

I have an ATI too(an HD4870 512MB) and don't any driver problem to run it at the máximum, without slowdowns! By the way...My SF4 benchmark screenshot:

So, how you can see, just a "lo-end" can do it.
It's no shame admit you machine is a "non-NASA" PC.
Or if you seriously have this machine you say, try to reinstall Windows, or defrag the HDD, or buy all new hardware... or give up playing games on PC, because PS3 and X360 is better than any PC(that quickly get obsolete).
Let's stop the fantasy dude! Post your real PC spec.

Sorry my bad english! I'm not a english native! :awe:
