First rule of software writing. No one reads the manual, trust me I know. Most people just unpack an archive and double-click away on the app. So it's best to nip it in the bud as they say.
One problem, and I'm being honest here, is you retain the name GemBench which implies it's GEM friendly. To make matters worse, that's partly GemBench's claim to fame, being tasking friendly.
So essentially you have taken it a step backwards, thus a certain amount of confusion is going to creep in. I realize the tasking and video mode affect the results, but regardless of that it has for many years been tasking friendly. If you are going to impose a single tasking OS with medium resolution, might consider renaming it to something more generic like TosBench or STbench and eliminate the confusion with its predecessor.
