Specifically, I am experiencing frame drops despite my efforts to address the problem. To resolve this issue, I have experimented with threading within the `onRender()` function and also attempted to separate the processing for each camera. Unfortunately, these attempts have not yielded the desired results, and I am still facing frame drop challenges. I am reaching out to seek your guidance on how to effectively resolve this frame drop issue when utilizing multiple cameras with the `sample_camera` application. Additionally, I am keen to know if there are specific strategies or best practices that can help maintain a consistent frame rate, preferably around 30 FPS. Thanks and regards, Khushabu ---

Dear @khushabu.talele1, Firstly, could you check with nvsipl\_camera application for your camera configuration and check if you are getting expected FPS? Could you share the DRIVE OS version, camera module and connection details? ---

Hiii @SivaRamaKrishnaNV, Yes actually I have tried Nvsipl\_camera code but still i could see frame drop Also as we have to disable gdm to make it working i dont want to do that. Hence I am trying sample\_camera code with multi-threading. DRIVE OS version - 6.0.8 Camera - Valeo with GMSL interface ---

Please refer to [Frame rate drops as we increase the number of cameras on Orin](https://forums.developer.nvidia.com/t/frame-rate-drops-as-we-increase-the-number-of-cameras-on-orin/262137) and see if running multiple cameras with [Recording Tools](https://developer.nvidia.com/docs/drive/drive-os/6.0.6/public/driveworks-nvsdk/dwx_recording_tools.html) has no similar frame-dropping issues. ---

Recording tool code is not provided Even I followed the same by creating multiple threads but I am not successful yet. So I more question Can CGF be useful to adress this frame drop issue? ---

Could you confirm if you’re using DRIVE OS 6.0.8.1? Which Valeo camera module listed on [https://developer.nvidia.com/drive/ecosystem-hw-sw#cameras](https://developer.nvidia.com/drive/ecosystem-hw-sw#cameras) are you using? Please be aware that there is a bandwidth limitation on the camera group B, as mentioned on [the “Maxim Integrated GMSL SERDES” page](https://developer.nvidia.com/docs/drive/drive-os/6.0.8.1/public/drive-os-linux-sdk/common/topics/nvmedia_sample_apps/Maxim-Integrated-GMSL-SERDES50.html). ---

Yes…I have not connected any cameras to Port B. 4 Cameras are connected to Port A and 2 to Port C. So May I know how much FPS we can expect when more than 8 camerasare connected to Orin and trying to run sample\_camera application from driveworks? ---
