Hi there,
I have Win7x64 with all the latest updates to the system and drivers (graphic (both), chipset, sound).
The problem is that in Counter-Strike my dedicated gt540m graphic card is used, but in Natural Selection it is not. I've search through google for my problem, but no it seems that no one has it before. In Nvidia Panel i have CounterStrike(hl.exe) and there i can change graphic card (i've tried to turn it off and i got fps down which means integrated graphic card was on), but i can't change it on HalfLife/hl.exe, the box is grey and only Integrated Graphic Card is shown, even if i tried in Global choosing only High Performance Graphic Card it does not work... And i had to add halflife/hl.exe to the list manually, it does not find it by itself. I tried even runnig HL.EXE, from where NS is installed, by right-clicking and choosin Nvidia card, but the indicator of nvidia optimus does not shown any program that is in use of this technology... Please help me...

    Hmm, there's a way to disabling the integrated video card in the Bios. Should be easy enough to do actually, you simply disable the integrated video card in the devices section somewhere and save/restart. Your motherboard manual should give you info on how to do this, you can always download a manual from the motherboard brand website as well :)

    Just make sure you stay away from memory timings, CPU/FSB frequencies or voltages and such, if you've never seen/messed around in the Bios settings! If you don't know what it is, do not change the settings. Just posting this warning as I do no know if you guys know about this stuff and what it can do (make it look like your PC is broken, while you can simply reset it back to default)

    However something as simple as disabling the integrated video card is completely risk free and would solve your issue :)

    Man, you are completely not reading what is it going about, for first: this is a laptop (look at dedicated graphic card, GT540M (M-Mobile)) not a PC and second: in a laptop you cannot change FSB and so on in BIOS :)
    So the issue is still unsolved and i do not see if it is going to be...
