My problem is this: I have the steam-version of the witcher 2: assassins of kings enhanced edition.
my system specs are as follows:
win7 64bit home premium build 7601
GTX 660ti (3gb gddr5)
intel i7 860 4x 2,80GHz
16gb of ddr3 ram
this should easily be able to run the witcher at 60fps if i tune down the settings a bit. but i am unable to reach more than 30 fps ingame, 35 fps in menus. changing my graphics settings does not have any kind of impact on the framerate, which sounds like the CPU is bottlenecking the games performance.
however, while playing, it looks like this: + Show Spoiler +
So that rules out a bottleneck, right? no core is under full workload, so there's room for more power.
now it gets really weird (i think). i am currently running the game at 1024x768 in windowed, with the lowest possible settings, always below 30 fps, around 24 fps in crowded places.
when i change the window however, and have the witcher running but do not control the application, my framerate triples.
i will be on the same crowded marketplace, but my fps instantly improve by a large margin.
what's causing this i do not know, but whenever i change the window, cpu usage rises. it's like the game is limiting the amount of processing power it has whenever i'm actually playing it.
things i have tried, that didn't help:
reinstalled the game
verified integrity of game cache
uninstalled and disabled everything that might have limited fps
reinstalled gpu drivers
i am absolutely lost here, and i hope that you can help me.
thank you in advance for any suggestions you have.

you can check your cpu clock speeds and temperatures with hwinfo
www.hwinfo.com
to see if you're throttling etc

one or two of the 4 used threads occasionally reach 100% usage when running the witcher, but they're far from running at the limit all the time. temperature of both gpu and cpu do not exceed 50°C while the problem is present, so i don't think overheating is an issue.

If CPU is at proper clockspeed (around 3ghz) you can look at GPU clocks and load%. It should be at normal clocks (maybe 1000mhz+) and if it's not at or near 100% load, it's waiting on something else in the system between rendering frames
|
cpu is clocked at 2,8 ghz, gpu is clocked at around 850 mhz when i'm playing, core usage about 30% or a bit lower. now, when i change the active window, the same thing as with the cpu happens - core load increases to about 50%, GPU D3D usage (dunno what that is) also increases from around 30% to 50%. so the game is drawing more resources and operating more smoothly when running in the background. what the fuck could be causing that?

have you played with the default graphics proprieties from windows?. nvidia has weird presets/overrides based on would be game settings.
see if you have "override application settings" or something like that there.

nope, not the case.

has nobody got an idea that i could try? this problem is extremely frustrating

In the nvidia control panel in the "manage 3d settings" section, look for "power management" and set that to "performance" instead of "adaptive".
Are you playing this game in borderless-windowed or fullscreen mode? Try the opposite mode.

adaptive was enabled, but setting it to performance didnt help unfortunately. i've tried it in fullscreen, windowed and borderless-windowed, but no change.

I can't imagine what's causing this. The GPU usage should be towards 100%.
Things I'd try:
In the Windows Control Panel on the screen that's about power saving, I'd open the details for the profile you are currently using and try setting "minimum processor state" to 100%. That should only be relevant if you are using the "balanced" power profile right now, not the "high performance" one.
I'd try closing all programs that you have running, including the antivirus.
I'd reset the driver's settings.
I'd try to see if disabling "HyperThreading" in the BIOS does something. It's in the CPU features sections.
I'd perhaps try to see what happens when disabling the power saving features for the CPU in the BIOS.
I'd try a different graphics driver version. If you use this search page here: http://www.nvidia.com/Download/Find.aspx?lang=en-us, you get a list of new and old drivers.

thank you for the suggestions, but none had an effect on my framerate
always exactly the same, barely reaching 30 fps, when i use another window, framerate goes over 100.
this is easily the most irritating thing i've ever encountered on a pc.
|
I'd write an email to the developer, with the first sentence exactly what you said just now, that the framerate is low when the window is in focus, but high when it's a background window, then continuing with a description that you tried fullscreen and windowed, you're on Windows 7, intel, nvidia, tried different drivers etc. If the right programmer reads that first sentence, he might immediately know what's going on.
|
Another thing:
Did you try different VSync settings? There's also the 3d settings in the nvidia control panel that can override this for games.
|
alright, i solved my issue. kind of. their support told me to redeem my key on gog.com to get a drm-free copy of the game and try if that version of the game worked, and it did. i'm not exactly sure why the steam version would have a problem like that, steam overlay is the only thing i can think of that is notably different between the two, but i had that disabled. so no real idea what caused it, but i can play the game at 60 fps now, so i'm happy.
