Today I tested one of my favorite series: Grand Theft Auto.
GTA III (old PC version, not the screwed up "Definitive Edition"): starts with sound, but black screen.
After compatibility setting "Proton 5.0-10" it runs without problems (thanks, ProtonDB!),
good stick-button control after a few button adjustments, very readable texts
1280x800 highest graphics setting, 60 fps, 9 - 11 watts power consumption, battery lasts about 4 hours
GTA Vice City (old PC version, not the screwed up "Definitive Edition"): starts with sound, but black screen.
After compatibility setting "Proton 5.0-10" it runs without problems (thanks, ProtonDB!),
