Performance seemed fine, I had no trouble running CS:GO on my NUC8i5. Didnt run any benchmarks though, and had to uninstall Steam as I needed the space, will test more later. Or you could just try it yourself, the entire Flathub library is now available on RetroELEC
Yeah I will, just dont want to install over my main HTPC with everything working. But I will try on my test setup soon
