It may not be quite as dire as you suspect. Firstly, system specs in games are always specced higher than you need in reality. Secondly, Linux OpenGL driver quality varies wildly, which is why they list only the two big vendors. IIUC Intel Linux drivers are actually quite good, so you may be in luck. I would reserve judgement.
It's just that the hardware that I'm currently running the same game on fell short of the minimum system requirements sort of put me off. Guess I'll have to report back after checking it.
