Resolume Forum

Hi,

I'm running Resolume 4 on Windows 7 64 bit desktop with i7 960 @ 3.2 processor and 24 GB RAM. I get 40-50 frames with a 1280 x 720 composition which is fantastic except when I activate the chroma key effect. My fps then drops to around 20. It's a great software chroma key and I really want to use it. I've got just an average graphics card. A Nvidia GT 520.

Does the chroma key use GPU acceleration?
Would I see any bump in frames per second if I invest in a better graphics card?


Thanks for any advice.

The Chroma Key is actually on the few plugins we outsourced. It's very accurate and GPU accelerated, but it's heavy on shaders and does some intense calculations. So the GFX card will have a great impact on performance, although i hoped you would get a better framerate at a resolution of 1280x720.
So the only thing you options you have is to get a faster GFX card or work at a lower resolution.

Thanks Edwin, appreciate your response. I'll try a GFX card and see if I can get a nice frame rate boost. I found a video card benchmark web site that uses a performance test "PassMark G3D Mark" to compare graphics cards performance with price.

This might be getting a little away from the Resolume conversation, but if you or any Resolume experts have any opinion on the best bang for the buck when it comes to a graphics card best equipped for FFGL GPU processing, I'd love to get opinions before I buy a new graphics card. Even a general opinion whether there is a performance/price difference between Nvidia and AMD/ATI for FFGL.

Thank you!
