less frames publish after filter in pyrealsense2

[MikoyChinese]

When I run my D435 with (848, 480) resolution in depth and color, I can get more than 30fps(max: 49fps) in my device, but if I try to turn on filter such as spatial, temporal filter in my code, I just can get ~20 fps in my devices. And I check my cpu, it has only 30% usage while after filter is up to 40-50% usage.

So who can tell me why can't I get 30fps in my device? How to solve it? Thx.

Best,

Applying post-processing filters has an additional processing overhead. The link below has advice for trying to enforce a constant FPS.

An alternative way to improve performance is to offload some of the processing work from the CPU to the graphics GPU if your computing device has a good GPU.

Hi @MikoyChinese
Could you please share platform details?
If you are building SDK from source please make sure you enable -DCMAKE_BUILD_TYPE=Release flag
