So I upgraded from a 5850 to a 670 EVGA 02G-P4-2670-KR (bought it the day it came out after reading a couple reviews). All in all the improvement is great. Crysis 2 runs effortlessly maxed out with 4x AA on my 1920x1080 screen. Unigine Heaven demo same deal. FPS gains are great and it has enabled me to bump up AA in all my games, Skyrim most noticeably appreciated. The only exception is Arkham City. Performance with DX11 features is poo poo with tons of fps lag spikes (70 fps to 3 fps for example). Internet research blames this on shoddy code. So I switch to DX9 and crank up PhysX. Things are much better, but lag spikes still happen. Whether inside or outside in the game the spikes occur when anything "happens", like the gpu is falling behind with rendering changes to a scene or scripted events. It happens when entering rooms, anytime the camera pans, when messages/audio plays, etc. It's very frustrating. On another side note, Crysis 1 saw an average 5FPS boost over my 5850. This is based off the GPU benchmark packaged with the game on Ultra with no AA. I'm figuring that's more to do with Crytek 2 engine being a resource hog, though I'd be interested to see if any GTX 670 users noticed either majorly improved framerate for that game or otherwise. More research seems to point to an issue with DX9 games under-utilizing the GPU, most notably in Unreal Engine 3 games. Someone on nVidia forums says a bug report was filed for a later driver update. Since GTX 6 series owners are still sporting launch drivers that might actually fix the problem. Any other GTX 670 users know what I'm talking about?

Star War Sex Parrot posted:Unreal Engine 3 was just never designed for environments that large, so the AC devs had to employ quite a bit of streaming stuff that seems to create hitches whenever you move around the environment. It drove me nuts that my 2600k @ 4.6 GHz with a GTX 680 was still getting hiccups so I switched to a 256GB Samsung 830 SSD and that cleaned most of it up. Fascinating! I am using a single 500GB 7200RPM drive and based on when the issues actually occur in game that makes complete sense. In that case it sounds like the ball is in Rocksteady's court to patch the game, but since the original DX11 "Fix" patches were released late last year there hasn't been a peep about them still working on it. Since it hit consoles first I can't say I'm all that hopeful they will. Is there a way of disabling texture streaming so all content for a level loads from the beginning at the sacrifice of longer load times?

Factory Factory posted:At the dev level, sure. But when you're targeting a console with 512 MB of RAM for both game and graphics, it's the So I looked into Arkham City more and the general consensus from multiple forums on the internet (Steam, nVidia, Rocksteady) is that everyone who tries to use PhysX or DX11 will have stutters and sharp FPS drops. What a shame. It looks like they're released patches more recently than I thought so maybe something may come. Mean time it looks like I'll be turning PhysX down or turning it off entirely. That now being clarified, I'm very happy with my 670. I'm thinking down the line when I feel more ambitious and finances permit I'll upgrade the rest of my kit and open myself up to dual 670's in SLI. EDIT: Guess 3D vision and Passive 3D don't work well together. Anyone know how much (if any) better 3D gaming is on computers versus on consoles?

thing to do not to change that behavior for other platforms.
