Trying different versions of proton on older hardware,

Bloons TD Battles ~

Proton 5.13-4: Does not launch, GE fork (5.21-GE-1): doesn't either

Proton 5.0-10: Works perfectly, GE fork (5.9-GE-6-ST): runs perfectly but without audio

Proton 4.11-13: Works perfectly, for whatever reason launches nearly 4 times faster then Proton 5.0

Proton 4.2-9: Launches just as quickly as 4.11 but crashes almost immediately
