Slow Depth Frames from SR300 Camera

Required Info
Camera Model	SR300
Firmware Version	3.21
Operating System & Version	Jetson TX2-L4T OS 28.2
Kernel Version (Linux Only)	4.4.38
Platform	NVIDIA Jetson TX2

Issue Description

As per the solution by @RealSense-Customer-Engineering on my last issue: #840 I installed L4T 28.2 with librealsense 2.10.1 and ran the provided patch. The alternate running issue was resolved but now the depth data in the cpp samples are coming with much delay; FYI the c samples, rgb camera in cpp samples and tools build by librealsense works fine. I am using https://github.com/syedharoonalam/installLibrealsenseTX2/blob/master/installLibrealsense.sh for librealsense installation, and patching it to support pixel format afterwards.

Lowering down the color camera exposure settings is correcting the depth data extraction. I don't remind facing this issue with L4T 28.1 with librealsense 2.8.1.

Hi @syedharoonalam
Increased exposure on the SR300 can lower the FPS considerably, creating the impression of software unresponsiveness. Could you clarify if you still facing a problem?

Thanks for the pointer Sergey. Lowering exposure seems to correct the problem.
