Question / Help Hardware encode with old ATI 5850?

[Zapa]

Hi!

I'm a happy user of OBS studio constantly trying to squeeze my old computer for best performance/quality balance. Right now I'm streaming Battlefield 3 playing at 1920x1200 and streaming it at 1280x800 30fps 6000mbps.

My last log: https://gist.github.com/11b2653eed8adba914ea794e5c9b7b32

I have reached a pretty good quality in my streams but my gameplay struggles sometimes having drops in framerate due to a high CPU usage. Not that makes the game unplayable but very annoying because drops are random and according to Murphy's law, always in the worst scenario. I have readed my ATI 5850 specs sheet http://www.amd.com/en-gb/products/graphics/desktop/5000/5850# and under the 'AMD Technologies' category it says it can handle OpenCL and "Accelerated video encoding, transcoding, and upscaling" through something called ATI Stream.

I wondered if I can use those implementations in OBS to lower my CPU usage. I wouldn't mind if that decreased a bit the pic quality. Or maybe there's something else around the 5850 that I could set up to increase hardware encoding?

Thanks in advance.

Hardware that supports AMD GPU Encoding. The first card that supports it is a HD 7730, so you won't be able to use it. Support for ATI Stream relies on the ATI Stream SDK which no longer exists and is likely discontinued in current drivers.

Thks @Xaymar for the answer. Yeah, i knew about AMD VCE and that my card didn't support it. That's why I hoped maybe that ATI Stream or OpenCL may be the answer.
