I understand if this falls outside your usual topic. I recently joined a video studio adopting virtual production. The machine runs an Intel i5 processor, 16GB RAM, and Windows 10. Camera angles are tracked via a Vive tracker and processed in Steam VR. The output feeds two HD projectors, giving a total resolution of 3840×1080. This system functioned well before, but during the most recent shoot one projector stopped working intermittently. We tried reseating cables and restarting the output, but neither fixed the issue. One suggested the frame buffer was losing data due to long runtime, while another thought the GPU couldn’t keep up with rendering. Both ideas seem questionable in my view. Could anyone share experiences with similar problems? Also, given today’s standards, do you think upgrading to a more powerful machine would help? I believe the workload is mainly CPU-bound, but adding a GPU with more VRAM might ease the strain. Camera tracking could be handled by the CPU and Unreal Engine rendering by the GPU—would that be realistic? Thanks for your input!
