I know synthetic benchmarks aren’t as useful as they might seem at first. Nonetheless, on a lark I decided to try Fire Strike under Proton Experimental on my Nvidia-equipped laptop. And it mostly worked. You’ll notice that the the system specs aren’t displayed, and it seems to think somebody was screwing around with system timer. At any rate, the magic number is…
No real reason it shouldn’t work outside of the checks for system spec, etc. Firestrike is quite old now and doesn’t make use of any special new fancy GPU features that linux’s windows emulation shouldn’t now be handling just fine.
