These last few days I have had a problem really bad. Since a lot of time that I was playing CS2D calmly and without lag. Suddenly start to get even with very few fps. It starts after I jugar about 5 minutes. I usually have 49 fps and then falls to 12-23-34.
The settings of my PC are:
Intel Celeron CPU 2.60 GHz
224 MB Ram
WinXP
No Video Card
My computing plays 46 process (including CS2D)
