@JohnW said in Improving camera performance: what is the theoretical maximum frame rate for the Tau camera? Is the virtual serial port not a bottleneck? The theoretical maximum frame rate is 50fps. And the USB serial port shouldn't be a bottleneck because the bandwidth required is low. Having said that, the realistic frame rate that can be achieved depends on lots of factors, such as the sensor configuration (integration time, operation mode etc.) and available resources in the host machine (CPU, cache, RAM etc.). The practical frame rate is usually between 20 and 30 fps. On the noise filter: There is no filter running on the Tau Camera hardware or in the driver. If this is a requirement, you'll need to add it in your software.
