Huge FPS problems in Shogun 2 TW [M17x-R1]

Hey guys, i'm having some trouble with Shogun 2 Total War. The FPS is really really low , and the sound is crippled (looks a lot like the throttling, but it's not , because i checked it with TS).

Anybody else experience trouble? ( zaro said he got some trouble too, in the A07 BIOS thread). Thanks!

P.S. : Stealth mode is not enabled. Both cards are on. Running 267.76 verde drivers with PCIE Gen 2 off. BIOS A06 with Throttling fix applied.

Game works using "Save Power" mode (running on integrated 9400M) but gives huge DPC Latency spikes with "Boost Performance" mode (running on dedicated 2x280M). Single-GPU mode in for the Shogun 2 profile in Nvidia Control Panel does not work!

 

Maybe also check with GPU-Z that the graphics cards aren't being downclocked, I doubt they are but who knows.

Also try enabling PCI Gen 2.0 just for a test of the game, maybe relies on heavy PCI Express bandwidth?

Sorry, don't have the game to be able to do any testing for you.

 

I don't have the game either, but i would disable SLi, probably the game is still glitchy.
I've read that the Total War games just don't really like SLI that well, my brother plays Napoleon and in SLI mode it just sucks.

 

Just did a quick bit of searching and katalin may be correct. It appears allot of Nvidia users are having issues with SLI on Shogun 2 and disabling it seems to improve their FPS.

Someone mentioned the beta 267.59 drivers have a Shogun 2 SLI profile, but I can't see them listed in the 267.76 drivers.

 

Yes, i did some research after this and it seems both Crossfire and SLi users are "affected". maybe they'll make a patch to fix this.

 

There is a profile for Shogun 2 in the 267.76 WHQLs from NVidia's website. Just installed them.

 

There is a profile in 267.76 indeed , just as in 266.58. The thing is , it says "Nvidia Recommended (Custom)" instead of "SLI".

I disabled SLI , and i have no bad fps indeed. Game is fully playable with the integrated videocard (in low settings of course). Hope they fix this soon

 

They didn't fix it with previous TT games so..i kinda doubt that

 

Did you disable SLI by just disabling one of the discrete GPUs? or both and run on just integrated?

 

I run it without a problem in sli with a consistent frame rate (haven't actually checked the precise numbers but surely more never lees than 30 , using custom settings everything ultra or high) try turning off depth of field and lowering the shadows (depth of field lower a lot the fps and as for the shadows I think there's a problem with them and the current drivers I read somewhere that the new 270 fix the trouble with shadows) I actually was surprised of how good it ran compared to previous titles

 

I switched from "Boost Performance" to "Save Power" mode. That means disabling discrete SLI GPU's and using the integrated card. I could try running on "Single GPU" mode in the Nvidia Control Panel , but i don't like stressing only one GPU...

It runs the same on the lowest settings possible , including resolution. This comes from the driver , i'm sure of it.

EDIT : I don't know what on earth just happened , but it seems to be working perfectly right now...

 

Sorry for double-post , but something weird is happening. Last week-end Shogun 2 was working perfectly and now it's back to the crippled FPS. I checked with DPC Latency Checker and there were spikes over 41000! (No throttling in ThrottleStop) I really don't know where this is coming from.. I will try and run a trace soon.

 

Sorry for triple-post , but it's the only way i can atract attention.

It seems the DPC Spikes are caused (as i was expecting) by nvlddmkm.sys , the same file that used to cause the throttling. It seems it's a part of the Nvidia display driver. Also DPC Spikes are caused by an "Unknown" driver , and ISR Spikes are caused by a driver named "dxgkrnl.sys" , some part of DirectX i guess.

Tried Empire : Total War profile and still the same problems.

 

This is how DPC Latency looks during a few seconds of gameplay in the campaign map in Shogun 2.

Also , tried Single-GPU for the profile in Nvidia Control Panel. Doesn't work.
