Serious CPU Usage spikes (1 Viewer)

[generalmx]

I'm getting some serious CPU usage spikes. In the menu, the average CPU usage is around 60%. The delay between each response to a button click is about 2-4 seconds, even on the main menu. I know it's the CPU load, as I was monitoring it from Task Manager and later Process Explorer. It's so bad, I can't record while MediaPortal itself is open, especially auto-timeshifting, or the video will drop below its intended FPS.

This system isn't too bad. Although I use a PCI video card instead of AGP, I've talked to people on IRC who have far better video cards (one a 7800GS), and they have the exact same problem as me. What's going on?

That Radeon isn't directx 9.0 card. CPU load is coming from the fact that your CPU has to do the rendering work.
