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...
