Clearly there is still an issue with hardware acceleration and your graphics driver. You may need to spend some more time adjusting the settings. Without actual system information we can't advise specifically, though.

If you have similar issues in Chrome, then something is seriously fishy. What does the extended info from the AE preferences say regarding hardware acceleration or for that matter the chrome://gpu/ info?

Well, Chrome says that nothing is working and that definitely is not right with an RTX 2060. I would suggest you boot into safe mode, go to the device manager and completely remove both your GPUs (really choose "Remove", not just "Disable"!) and let Windows automatically check for drivers after another reboot. Inbetween it may also be worth checking your BIOS/ UEFI and see if something is flagged there e.g. in terms of PCI timing or voltage.
