UK_John: If you look at Outcast trailers of the day, you could see that Cutter DID run through the Riss! So I would disagree with comments that Appeal initially wanted you to walk through Riss!
Cutter also ran through the Riss when I played using a CPU slowing program. So if players want that functionality they can try using a slowing program instead of the fan patch, but it would only work on a non-GOG version since GOG has incorporated the fan patch.
But, CPU slowing programs are kind of annoying... one has to find the exact right setting to get everything working without crashing the game, and even after I found a sweet spot I think certain other things in the game weren't working. My HAWK MK8 seemed to shoot straight through enemies without hitting them, for example.
Overall, the fan fix (included in the GOG version) is probably the easiest way to get the game running, even though Cutter will be forced to walk through the Riss fields.
Also, can't Cutter ride a Twon-ha through the Riss instead?
