Most have probably already tried this. I have a high end gaming system, but for some reason was still experiencing great lag with the SA client. So I did not realize this was possible until yesterday. You can open up your nvidia control panel and manually change specific games. So, I changed SA settings to all performance and lowered everything in the client as low as possible. Now I can play the client for about an hour before it starts lagging whereas before I could only play for about 10 minutes before everything would start freezing up. Hopefully this can help some ppl out.
