BIG Problem!! High FPS but jittering!!! Please Help

[Simon Wallenda]

Hi Crazy People!

I have a big problem that when i play vids (DXV Resolume-Demo-Vids or others) and i set the resolution higher than 640x480 the vids begin to jittering and i see this too in the timeline of the vid. the fps was 60fps by 800x600 but on this resolution it begins to jump in the timeline of the vid, not so mutch but its not acceptable. I try a lot and search a lot in the internet and in this forum and buy yesterday a ssd hdd the speed was better on osx but fix not the problem in arena The CPU speed was 50% of 800% wen i run Arena. I try Arena 4 and Arena 4.0.1. Now i have no more ideas, please help me i need this till friday.

Hardware: MacBook Pro early 2011 i7Q 2.3Ghz; 8GB; 120GB SSD Vertex 3; 500GB Apple 5400; TripleHead2Go

I have the same laptop, but i've switch out the standard hard drive for a 7200rpm drive. I run all my video at 1280x720 and run into no jittering. Running the CPU at 50% is almost normal for this I would think, as these chipsets come with graphics built in, as well as the extra card for graphics switching. Try turning off graphics switching in the energy preferences

yes make sure that your system settings are set to high performance graphics, no energy saver.
