There are also various effects that can't be captured by that percentage, such as RAM usage, PCI Express usage and waits due to CPU/GPU synchronization. 80% CPU usage doesn't mean you're using 80% of the computation power of your CPU. For example, your CPU frequency depends on the load, and is not taken into account in the CPU usage. GPU: Zotac Nvidia Geforce GT630 (GK208 28nm: 384 Shaders / 8 ROPS) Zone Edition Passive Cooling 2GB DDR3 1800Mhz 64Bit (14.4Gb/s)ĬPU usage is a very inaccurate way to measure actual performance. MEM: 8GB DDR3 1333 (2x4) Patriot value (128 bit dual channel: 21.3 gb/s) When using SSR with ultrafast preset, give good quality but affect performance (CPU % around 25 to 30%), with obs-studio with 3750bitrate loss some quality but performance improve (CPU % stay around 15 a 18%) and now with ffmpeg libnvenc with 3500 / 4000 bitrate in various titles improve performance and quality too compared to regular obs-studio with same bitrateĬPU: INTEL Pentium G3220 (Haswell 22nm) 3.0Ghz (Dual-Core) Stock Clock mrdeathjr28, can you do some performance tests with SSR if you can get it to work?" I'm not convinced that this will be faster than x264 since there's a lot of overhead caused by the additional copies between video memory and RAM. "Looks like they are using some of the same names as x264, like 'preset', 'tune' etc.
