I've yet to get possession of my new place, so I only have Mass Effect, Crysis, and my Steam titles to play ATM...I chose crysis becuase the disc was in my drive already, and after reading Cranky's post, I quickly snapped a video. I could make many more vids showing many issue like this, and other strange behavior when running multiple cards. I can throw more vids up in the next couple of weeks...but I gotta move and get unpacked first!

In regards to drivers...all of them do it. I've tried every driver that supported Crossfire since day 1, have been running Crossfire X850's, X1900's, X1950's, HD2900's, HD3870x2's, and now 4850's(until 4870's come, and then 4870x2's).

Cranky, in regards to specs, ASUS Maximus Formula SE, RD600, XBX1 and 2, MSI P35, ASUS P5K, DFI BloodIron, E6600 @ 3.6ghz, E8400 @ 4.25, Q6600 @ 3.6ghz, QX9650 @ 3-4.5ghz( less cpu speed= less stutter), Ram doesn't matter (got all versions of DDR2, promos, elpidia, samsung, Hynix, Micron, 1-8gb makes no difference), Enermax Galaxy 1000w DXx, PPC Crossfire 750 (red one). XP Home, XP pro, Vista 32 and 64, nothing matters. In Crysis, I will say that this problem is less @ 16:10/16:9 resolutions in comparison to 4:3(which the video was shot in, 1280x1024). Whole system is water cooled, nothing tops 40c.

THere's no way there's a cpu/gpu limit here....low res for the video, and higher res plays much better. It's realyl does seem driver realted, and I'm sure it has to do with either memory management, or traffic scheduling, as common resolutions exhibit this behavior far less than un-common ones...1680x1050 is nice, 1920x1200 is running into gpu limits, 1440x900 is like butter, but jaggy.

Beleive me, I'd love nothing more than if issues like this were not a reality.

I've spent alot of money on hardware chasing decent rendering on my monitor...the big bastard is so dman fantastic, and so friken' crappy at teh same time...
It looks like you have no hardware probs causing that problem, maybe im not noticing due to gaming mainly 1650 or 1920.
It does appear as if res is too high causing the variations in speed, but we know thats not the case. Do the fps drop when this is happening?
I wonder if todays LCD monitors are adding?
Does it with crt i spose?
But dont beat yourself up over that prob dude, just grab the new X2 when released like the rest of us who enjoy the fastest cards, if only for a little while
