Is this a bug in this GFX driver? Or is Windows 10 no longer using old driver's scrolling code?Ĭan this be somehow configured to use GPU hardware acceleration in Win10? Or could any older driver version fix this problem? So to me it seems that scrolling is not using any GPU hardware acceleration at all, but is solely rendered on the CPU. But when scrolling in any window (File Explorer, Internet Explorer, Word, Firefox, whatever, updown, leftright), everything gets slow and the CPU usage peaks up to 50 % while scrolling (using up to 1 of the 2 threads of the CPU dual core). So obviously no CPU activity involved in moving windows, which is good. Now I can see, that the GFX acceleration is working fine, when moving any window with the mouse: smooth movement and CPU usage in task manager is flatlining near 0% while moving any window.

There are no errors logged for the GFX driver and there are no unknown devices left over in the device manager. (its version number seems even higher than what Intel offers for download on ) Mobile Intel(R) 965 Express Chipset Family (Microsoft Corporation - WDDM 1.1) The automatically installed Intel GFX driver version is 8.

Windows 10 automatically found and installed an Intel gfx driver from MS servers for this - it did not install the CPU-rendered Microsoft default GFX driver and I did not have to download drivers from by myself. 965 express chipset is said to have a GMA X3100 GFX chip. I have installed Windows 10 (64bit) on my notebook with Intel 965 express chipset and Core 2 Duo T7500.
