The heapsize will not provide you performance, nor the task manager stuff. CS 1.6 is game based on an engine created at 1998, so it was designed, that it will not need lots of resources to run fine. In your case don't use the heapsize argument, CS will take the ram it needs( usually around 200mb ) because it just doesn't need more. About the cores. CS is single threaded application so even with this task manager hacks it will actually not use the two cores, it is not possible because the today operating systems can't share one thread on two or more cores and you can't do anything to change that. Don't be afraid of that btw, if CS is taking enough from core 1, other programs will run on core 2( the OS will handle that, so don't think about it ). To get more FPS in your case is to get some nice video card(CS is old but integrated videos just sucks). To get 100fps even the very old GeForce 5200 will do it, I recommended you 8800 GT because you may want to play some modern games that requre more resources, but if you just want to play CS any GeForce from series 5xxx will handle it fine.
