Must be playable. On my GPU (GeForce 840M) in worst cases emulator gives 8 fps. Usually it's 11-13 fps. When looking at ground - 20+ fps.
On stronger hardware it'll be playable.
It should be moved back down to ingame. It frequently crashes, which combined with infrequent saving, requires you to replay a lot of missions very tediously. I'm unsure if this is a recent problem or if the other playtesters didn't get far enough to experience it. In my 30 minutes of playing I got it to crash 3 times, all during the pre-rendered cutscenes.
It wasn't moved as there were no screenshots in that report so the script that moves things round didn't pick it up
You will need to do another report on a newer version if you want this to be moved back
