I have a Dell XPS 8900 desktop, stock, 1TB HDD, 16GB RAM, Nvdia GeForce GT 730 graphics card, running Win 7 Pro 64bit.
Yes, I know this isn't a high end graphics-type machine, but I need to do some animation and graphics work and it has been crawling badly.
But it seems to be perhaps something other than just being underpowered for the task. I needed to do some Skype conversations and got a webcam yesterday (Logitech C920) to connect to the computer. I can't get a clean video signal from it above 360p. Anything higher and I get this jittery video that I captured on my phone in the Youtube link below:
Do I need a better graphics card? I would have hoped that the stock card would have been able to handle at least a 760p video conversation. Or is there something else wrong with the hardware?
