i havent tried any games exept the keens yet, can't find were all my old toys are but

specifily i am talking about keen 4

when i run keen the graphics are jerkey. Now the music plays fine and crisp. I can take my cpu cycles upto 8k untill the music begins to break up, so i realy don't think it's a prosesor power ishue. I have a p4 2.4 gig of ram grofce 4. My frameskip is set to 0
Would be funny if the game was always like that and i just never notised. it's only realy aparent when the level scrolls. Alot more aparent if i runt he game full screen

my guess is dosbox is not syncing the fps

any help on resolving this would be very apreshiated
