Trouble in Terrorist Town 680M underutilization

So whenever I fire up a game of TTT my 680m always downclocks to around 500MHz and hence I always get below 60 frames, changing the settings doesnt help, this happens with high and with low settings, vsync doesnt help either. I play at 1440p, no overclocks

 

How is your CPU responding? Is this a known issue with the game? For example, in Splinter Cell conviction (I think it was conviction...) when playing multiplayer the game is forced to max 30fps and to the fps of your partner or something like that, so you always get underutilization no matter what.

Maybe this game is similar in that it is hardcoded for underutilization via fps locking or something?

 

I dont know if its a known issue, dont think so. CPU is fine. I think the problem is that the game is so undemanding the GPU clocks itself down, temps are around 50 degrees which is a joke, thats almost idle (not quite).

 

Even if games are not demanding, if there is no fps cap, the GPU runs at full (while producing huge fps numbers).

There is no reason for the GPU to underutilize itself if there are no fps caps, or hardcoded into the game.

 

Thats what I thought, the game should run just fine, its like enduro all over again. I have this with fifa 13 also (gpu downclock) but there everything is fine with vsync.

you think there is a cap?

edit: ok so i tried 1080p low settings and I was getting ~55 frames, but the gpu clock was at 135mhz, basically idle speed as were the temps.... I dont know what to do here...

 

I'm not so sure about this. I mean GPUs don't "know" that it is a game. It is the drivers' job to do that. May be they didn't have that support for the game. That would mean that the GPU wouldn't be able to distinguish between say a movie being played or the game.

 

any way I can tell the gpu its a game, exept for selecting dGPU in the nvidia control panel for the game?

 

Try this. Rename the TTT executable to something else, just put an underscore after it so it's TTT_.exe instead of TTT.exe (or whatever executable is). Then manually select the new renamed executable (TTT_.exe) from the nvidia control panel and set it to dedicated GPU. I've had to do this on a few occasions where it would choose settings for the wrong game or think it knew the best setting based on the exe name, but it's not always that smart.

 

I don't know if this will work. TTT is party of gary`s mod, which in turn is called hl2.exe so basically half life 2. Should i try and rename hl2.exe the whole garrys mod?

 

sure give that a try. Easy to switch back.

 

just tried it, didnt work
Ill try reinstalling the game

 

This is a known problem with the branch of source gmod and tf2 run on.

I've spoken to Garry about this issue and he refuses to acknowledge it

It happens on both my machines with optimus when using internal display.

When using the external GPU I have with one of the outputs directly on GPU I get great performance.

The problem is directly related to Optimus driving the external display.

 

so internal display/ integrated GPU (HD4000) would work fine?

 

At 1920x1080 you may just scrape along, saying that at 1920x1080 I get better FPS on my HD4000 than Highly O/C'd 650m in GMod and TF2.

 

Yeah 1440 would just kill the hd4000! What kind of fps do you get on tf2? And low settings i presume with the hd4000?

Ok just so everyone knows, the game runs fine now on the iGPU with about 80-100 frames@1080p, might try 1440 afterwards, anyway thread can be closed

 

Glad that helped!

Interesting how you get higher FPS than me at 1920x1080.

 

its all low settings, no AA/2x AF, also the server wasnt so crowded... maybe thats it
