Camera board • libcamera-raw framerate V3 module Raspberry Pi 4

Hello, I am attempting to use the libcamera-raw program on a raspberry pi 4 (running Bullseye) to capture raw image frames that I can process later.

When I execute the function: libcamera-raw --list-cameras

I get the following output:
Available cameras
-----------------
0 : imx708_noir [4608x2592] (/base/soc/i2c0mux/i2c@1/imx708@1a)
Modes: 'SRGGB10_CSI2P' : 1536x864 [120.13 fps - (768, 432)/3072x1728 crop]
2304x1296 [56.03 fps - (0, 0)/4608x2592 crop]
4608x2592 [14.35 fps - (0, 0)/4608x2592 crop]

However, when I run the libcamera-raw -c configFile.txt
where configFile.txt is:
timeout=3200
frames=180
output=test_0.raw
metadata=metadat.txt
nopreview=1
mode=1536:864:P
awb=daylight
gain=1.0
denoise=off


I collect only 89 images over a 3.2 sec image capture period, or approximately a 30 Hz framerate (a factor of 4 below that expected). Interestingly, I get the same number of frames collected if I increase the requested size of the image to 2304x1296.

Has anyone been able to increase the framerate using the V3 camera modules on the raspberry pi 4?
