No fps loss here, personally, I don't have a monster CPU by today's standards, either.

It's unreasonable to accommodate all conditions and disabilities (especially those like epilepsy that often go undiagnosed because the person has never had a triggering event before); this is why all video games carry warnings about things they might cause. Nobody at SE could have predicted this, and it's too late to completely redesign the job so a few people don't feel sick, and even if they did redesign it, that's no guarantee that somebody else wouldn't feel sick.
