Hi there.
Recently I have noticed that whenever I run a graphically intensive program (such as a new-ish game), my framerate will decrease over a five minuite period.
Before this problem occured I could run the the same games perfectly smoothly.
I had a similar problem to this a few months back, in which I found that the large vent on the side of my computer was almost completely blocked. Cleaning the dust away from that vent returned my computer to normality.
However this time the vents on my computer are still clear, and opening up the computer revealed virtually dust-free innards.
Could this problem be related to over-heating like last time? I have no way to read the temperature of my computer (that I know of), it doesn't have an external thermometer.
I don't know if this'll be any help, but here is a screenshot of my CPU usage while running one of the aforementioned games running a rolling demo. The rolling demo loops around every 2 minutes. I did not touch the computer during this time. I've marked the time when FPS drops become very noticable (from ~30 to jumping between 5-20) with a red line.
On the same rolling demo, I took screencaps with the FPS counter showing every 30 seconds from starting the program.
These were the results:
Time - FPS
0:30 - 53
1:00 - 62
1:30 - 65
2:00 - 56
2:30 - 50
3:00 - 31
3:30 - 12
4:00 - 15
4:30 - 15
5:00 - 5
I don't know if any of this will be of any use to anyone, but I thought I'd include it none-the-less.
My system specs are as follows:
Intel Pentium 4, Single Core, 3.4 GHz
Windows XP Home 32bit (Service Pack 3, all security updates installed)
2x2 512MB DDR2 RAM (2048MB of RAM in total)
ATi Radeon X600 PCI-E Graphics Card
360GB Hard Disk (7200 rpm, 53GB space free)
Advice would be very welcome, I'm at wits-end :sad:
