Grimrock

I had to disable vsync in order to get a stable framerate. Also triple buffering works. But when iam using vsync the game really comes to a crawl when certain effects appear. Try it out.

Also some Notebooks do not recognise when a game is loaded and thus do not clock up. I recommend checking the energy settings and set them to highest performance when the power cord is plugged in. Since heat is not your issue and even crysis ran well the above may help.

Good Luck!

The game acts weird the whole time. One tile I am at 60, on the other when facing a wall I go down to 25. This applies to all areas. It either hates my GPU, which might be the case since mobile GPU are stressful to use.

I also checked how much power the game is using. GPU is utilized in 100%. I have to check the CPU though.

check also the GPU temperature (GPU-Z), maybe the GPU already periodically "throttles" down the clock to reduce the (over-)heat... consider then reducing the frame rate limiter to somethign significnt lower then the current 120FPS to keep the temeprature in a reasonable range...like 40FPS.

Could you please enlight me on this frame limit? How do I do that? I didn't see any options :/

That option "maxFrameRate" is inside the "grimrock.cfg". The default value is set to 120 and what is does is setting the hard fps limit for the LoG engine so it will not render more fps then this value even if the GPU could do it.

This has absolutly nothing to do with your problem.
If it's not overheating i'm with eispfogel: the GPU might not get enough power to do it's work properly.

Oooh - another thing to try on a laptop. Make sure your Windows Power Settings are on "High Performance". It usually defaults to "Balanced", which is normally fine - but some laptop manufacturers will also make it so that your CPU doesn't run Turbo Boost when not in "High Performance" mode. Probably only a small chance this is what's causing your issue, but no harm in trying eh?

I have Lenovo Y500 which has 2x 650M and Forgotten River level at 1980x1080, all high is about 25-30 fps.
765M alone probably is not as fast as 650M SLI (?).

Looking at the performance of the GT 650M those fps values sound ok for me for a SLI pair.
A single GTX 765M should not be that far behind, between 10 to 20 percent less.

Yes, thats true Iam not complaining my computers performance. LoG2 is playable.

Back in old days I played Tomb Raider without any 3d card , there was one jumping sequence where you simply had to press that sequence blindly because fps was something like 1 , game was however running perfectly at background although it could not update display. It took couple days and countless retries to get it right

The GPU is operating at it's highest clocks Everything is working a-ok. I am still investigating the CPU. Maybe something does not click and it doesn't clock up or even recognize a program being run.

Laptop is switching autmatically to high performance mode. Just in case I did it on my own. Same effect.

As for the SLI. If LoG2 does not support SLI, the game most probably is using a single GPU only. You are still way better off than me

Gentlemen, it might as well be that LoG2 engine does not handle the open spaces well, or there is more optimization to do.

All in all, great game I will play it in 480p if I have to xD

I will update you on the CPU performance once I am done with work and have some time for testing

Thanks for all the replies and help! (hug)

Yes it does not support it as default, however I use forced SLI drawing. Without it, FPS at Forgotten River level is something like 10-20.

I'm getting a similar framerate issue. In a Dungeon environment my game runs at least 60fps, but in forest environments it drops down to around 18fps. I've already disabled "wait for vertical sync" which helps a little, but the only option that makes a real difference in frame rate is turning render quality to low which solves the framerate, but makes the forest look rather ugly and thin in comparison.

Processor: AMD FX-6100 six-core ~3.3GHz
Video: NVIDIA GeForce GT 640
16GB RAM

I am back with some test results. Please bare in mind that I am not an expert at this so I will just provide you with some raw data In my opinion, the game does not utilize all the power at its disposal. Then again, it does not need to because it is not that taxing on the system. So why the low framerates? :< halp!

This is the highest usage recorded:

GPU operates at maximum clocks. CPU when in maximum performance mode, 3.6GHZ. Bare in mind that this baby runs Shadow of Mordor in 1600x900 on High/Medium details on a stable 50+ frames :<...
