If you are streaming above 30 FPS, the CPU consumption will be really high, dragging the computer to really slow.Īdjust resolution and frame rate in OBS: File > Settings > Video > Output (Scaled) Resolution > Common FPS Values > OK/Apply. Īs for the frame rate, we recommend you have it at 30 FPS or lower. As higher res causes more strains on CPU, the conventional way to lower down CPU usage is to downscale your output resolution.

As 1080p doubled the numbers of pixels in each frame, the CPU usage will be elevated accordingly. It makes sense that CPU may have kicked into a higher performance mode running at 1080p compared with 720p. Downscale Output Resolution and Frame Rate It depends on what youre streaming though. A few buddies of mine have tried it, and at the same bitrate, x264 looks better. The higher the encoder preset ( Max Quality), the lower consumption on CPU, the better image quality The lower the encoder preset ( Low-Latency Performance), the higher consumption on CPU, the lower image quality. As the post states, it uses very little CPU. With the chart, you could have a brief idea on the three encoders. The chart below tells you the differences among x264, NVIDIA H.264 and QuickSync H.264 in OBS Studio and their relative pros and cons comparing with the rest two.

As x264 is software encoder and H.264 is hardware encoder, the difference between encoding in x264 and encoding in H.264 is worth to note: technically, x264 consumes more CPU resources but exports with high-quality graphic images while H.264 costs less CPU consumptions however guarantees low quality in graphics. In OBS Studio, there are 3 encoders for users to choose: x264, NVIDIA NVENC (H.264), and QuickSync (H.264), which are CPU encoding, graphics card encoding and core graphics card encoding respectively. As a AVC Hardware encoder it certainly looks like one of the best around and would certainly use it for realtime.30 posts I ran some tests on some clips and decided to post some results. don't use x264 presetsuperfast or ultrafast for streaming, as they produce way worse output than even Quicksync. This will not interfere with your game at all.

The following content will show you how to deal with overloaded OBS and provide you with both step-by-step guides and explicit pictorial instructions. if you have Quicksync available, use Quicksync with presetbalanced. This allows for much more power-efficient. This headache issue can be soothed by adjusting software encoding and hardware rendering parameters. Unlike video encoding on a CPU or a general-purpose GPU, Quick Sync is a dedicated hardware core on the processor die.
Apart from some common issues such as inadequate hardware - your hardware has not be updated yet, insufficient network - your internet connection is too weak or slow, too many programs running at the same time - your CPU is used by too many other programs, etc., the most possible reason why your OBS encoding overloaded is that your parameters are too high for your computer to handle.
