A think it´s 32mb of ram on s5500hcv.
After a installed a Nvidia card with 64mb it got better but not good.
So a reinstalled the onboard Matrox driver.
As suggested a updated the nic driver to 14.6 and then a played around with the SEWMDx64.exe inf tool for the Matrox card, and now it´s acceptable but not good.
A think this problem is a combination of different things, a hope the address this issue asap.

When a installed the matrox driver with "SEWMDx64.exe 2 8 1 1 1 1" it maid it better, but if this is the right way to do it a don´t know.
