Asus A7N8X-X: USB mouse CPU drain...
|Reported by:||Luposian||Owned by:||nobody|

When I first switched from my Via chipset motherboard (which had horrible CPU usage; upwards of 50%, every time I moved the mouse) to the Asus A7N8X-X, I was amazed that my CPU usage was night non-existent, when moving the mouse. Nothing (even GLTeapot) showed any loss in speed, when moving the mouse.
This was about a year or so ago. I was not having this problem when I was having the audio issue with this system about 7 months ago (http://dev.haiku-os.org/ticket/5414).
Now, I try out the latest builds, and this exact same system now shows about a 15-20% CPU usage when moving the mouse. It's a small increase, but GLTeapot slows down quite noticably as long as I'm moving the mouse.
I assume this is because, as Haiku progresses, older chipsets get left behind and are either no longer properly coded for or are otherwise ignored during improvement cycles.
If my assumption is incorrect, I'd appreciate clarification as to what is causing this. I no longer have a modern computer (this Athlon XP 2000+ system is it; had to sell QuadSlacker for family reasons and my Athlon 64 X2 system is being used at our church for audio work) and was hoping Haiku improvements would not result in older system "deprovements", performance-wise.
