Well, i have been having issues with hammer and XP SP4. It will be going at the normal 100 FPS then after like 10 - 20 Seconds it skips down to 5 FPS. So i would restart it. It would do the same thing. For some reason my laptop has been having this issue also. Ive had Windows 7 on my laptop and it would run hammer at NO lagg, But i decided to try xp on it. So i did, got hammer, and the source game to run it. And what do you know… It laggs just like i explained on my desktop.
Now this is a weird coincidence since i can run gmod at a 70 on all high.
For all the XP users out there. Are you having this issue? Did you fix it if you had it? Any support will be good
