Before the Enhanced edition I ran TW2 on Ultra settings with Ubersampling on, and the game was fine. I had a break and decided to pick up the game again, but now the game is unplayable. Its weird because the first two minutes of play, everything is fine. Then the FPS slowly drops until its staggering and unplayable. Its the same all over the game. I tried to make a new game, load different saves etc. The funny thing is that the same thing happens even with the lowest graphical settings(its more stuttering then tho). The FPS just drops slowly until I restart the game, and then its fine again for two minutes until it starts dropping again.

Operating System: Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1
Processor: Intel® Core™ i7 CPU X 990 @ 3.47GHz (12 CPUs), ~3.5GHz
Memory: 24576MB RAM
DirectX Version: DirectX 11
Card name: NVIDIA GeForce GTX 590
Display Memory: 4048 MB

I have the latest Nvidia drives, 3.10. Other games are fine... so please help.

the last nvidia drivers the 310.90 had mad issue with the 590 and 690 cards SLI in general if you installed them the first day those drovers came out I would suggest re-downloading them and reinstalling them or roll back to an older driver set.310.70 should work fine. If that fails to work let us know.

Also do you monitor your cpu and gpu temps? may have an issue there

[RSIK4]

please disable ubersampling option

In the line of thought which Geralt The Riv brought up: disable SLI in the nvidia Control Panel, so that the game only runs on one GPU and see if that solves the problems.
SLI can be the culprit for many performance and stability related issues.

@ Geralt: The drivers is not the problem. I had this issue with six different driver versions.

@ RSIK4: The problem is not constant stuttering or low FPS. As I said, the game works perfect when I start the game. After 2 minutes of doing anything the FPS slowly drops and the game start to stutter. Even at the lowest graphical setting. Ubersampling has nothing to do with this problem.

@Skyclad: Funny thing. Disabling SLI fixed the problem. Yet disabling it means I have to play the game on lower graphical settings Thanks for the tip though. Now any tip on how to get the game work with SLI ?

You could try the new Beta driver from nvidia which has been released today: http://www.geforce.c...ers/beta-legacy

If that doesn't solve the problem, I've found a guide (unfortunately from 2011) how to enable SLI via nVidia Inspector (though I don't know if that fix works with today's video drivers): http://www.overclock...2-sli-fix-guide

oh and a quick question: You posted that you have played the game before without problems, did you use the same video card back then?

Edit: I just had another idea: check in the nvidia control panel the power management setting for your card. On default it should be set to "adaptive mode" or something like that. Set it to "Prefer maximum performance" and see if that changes anything for you.

Beta driver didnt work but nVidia Inspector revealed something interesting. The GPU temperature accelerates to 99C, this might be the problem. The other GPU was about 77C. I wonder what to do next... />

Edit: Yes I used the same video card back then.

Hm, maybe it is a temperature problem.
Did you test other games or applications which are graphics intensive (i.e. Furmark or Battlefield 3)?
It could be that the gpu clocks down to prevent overheating, hence the dropping of fps after a short period of normal frame rate.

Yes, I got the same problem in Diablo 3. I know that's not an graphic intense game, but certain ares of the game are badly coded and thus becomes graphic intense. The same thing happens, after 5 - 10 min of play in those areas, it stutters. I'm gonna demount my card, give it a go with the vacuum cleaner and see what happens.

Update: Well never underestimate the power of dust!!! I unmounted my card, spent a good 10 min vacuum cleaning the rib, the fan and whatnot and now temperatures is stable and the problem is solved

The GTX 590 is an extraordinarily difficult card to cool correctly. It's been troublesome ever since it came out. A BIOS fix from nVidia didn't solve the problems. This game will expose cooling problems that virtually no other will.

Airflow in the case is one key. Your airflow should be arranged such that the cooler does not suck hot air (for example, off the CPU cooler), and air coming off the cooler is exhausted to the room.

Some users have had good luck with forcing AFR2 mode. Seems to distribute the load between the GPUs better than AFR does.

Others have had to resort to forcing Vsync on (which caps the GPU load at 60 fps or whatever your monitor frame rate is) or water cooling.

Hehe, glad you could solve it so easily. Better than to take the card apart and re-apply the thermal paste

Glad it worked for you. Yeah, dust bunnies are the mortal enemies of high-performance computing.
