I have a similar issue, where I mainly notice that the maximize window animations of windows which exceed about 3/4th of the full 4k display size stutter extremely (10 fps or so).

I've done a lot of search on the internet before posting here, I found few cases like me but none of them had a solution or any useful information so I am desperately seeking help from you guys. I have a desktop running on HD4600 (4790K) it's very smooth and I faced none of those problems with it, and I find my Laptop very laggy and sluggish compared to it. Now to the funny part, none of those issues are present when I decrease the resolution from 4K to 1080p, everything is smooth like it's supposed to and no playback issues, I am pretty sure that HD530 can handle Windows 10 UI animation, web page scrolling and decode a 4K video just fine. Just trying to move Spotify window around is like 7fps. When I watch 1080p movies on MPC-HC in fullscreen when trying to change volume with arrows/mouse wheel it also lags, and 4K videos are lagging and sound goes and comes back in 4K playback. The problem is: Windows 10 interface is laggy when opening/closing start menu, maximizing/minimizing windows, opening task view, scrolling web pages like facebook on chrome and more (FPS is way bellow 60). I am using Windows 10 Pro 圆4, cleanly installed and fully updated with all drivers updated as shown.

Somewhat nerve-wracking due to many reboots, several long phases without visible progress, and lots of scary messages scrolling by fast.I'll start with my specs and list of my driversĦ700HQ, HD530, 4GB GTX 960M, 12GB DDR4 2133MHz, 1TB HDD, 4K screen. Regular installation of the Big Sur Public Beta Update from 10.15.5 worked with no actual problems. But I'm not going to touch it for a while just to find out. I added both at the same time, and it's therefore possible that either one is enough to get it working. Ignorance is bliss!)Īlso setting device-id and using the complete-modest option. (Had I known that to be the official maximum, I would have probably stopped trying at that point.

The latter would either just turn black during boot, or not allow any resolution above 1920x1200. I'm using ig-platform-id 193B0000, not the recommended 1912000. Building a CustoMac Hackintosh: Buyer's Guide
