Ive tried everything.. I want to run Arena on "high settings", I've pumped the in-game detail bar all the way and i still get framerate issues/lag

I've set memsize=64, cycles=max, cputype=auto, core=normal, and ive already tried pressing both ctrl-12 and ctrl-8 for frameskipping/improved performance.

I've also tried changing the cycles=fixed 30000 but didn't notice any performance increase.

This is kind of a big deal to me, I can't force my dosbox to play arena at a higher cpu speed, whenever i ctrl-12 it cant go past 105%. I've also tried to edit some files in arena.confg to change the max cycles from 15000 to 30000 but I realized i can't edit the file. :/ Any help?
