~250 games testet, about 90% worked without issue.
Some games were hard coded to avoid Intel graphics and would use the AMD iGPU by default (even a newer title like Alan Wake 2 did this), but after disabling the iGPU, most of those were fine.
I think like 10-15 games didn't work at all or had basically unplayable performance, maybe a few more with graphical glitches, some minor, some more noticeable.
