Saying "many" games work better with GE is misleading I think, though perhaps technically true. The vast majority work out of the box with regular Proton. Reaching for GE is definitely the exception rather than the rule in my experience.

Valid point! For me, the FSR3 -> FSR4 was such a big boon of performance and graphics quality it made GE Proton (with the PROTON_FSR4_UPGRADE=1 flag) the easy choice for most games that supported FSR3. Luckily, it seems Valve has just added this to their Proton, too!

Not needed for working, but I always find GE's improvements on performance much better than stock Proton. I usually default my games to it anyway, since it is always installed

I found it to be the case that while many games worked with stock proton, I often (most of the time) got much better performance from GEs proton.

Back in 2018, using the Glorius Eggroll fork basically mandatory. Nowadays? Not so much.

One of the biggest blockers I remember was that Valve refused to support some of the proprietary video codecs developed by Microsoft that only have a working legal decoder on Windows, but eventually they decided to just show a fallback image if a cutscene couldn't play.
