So basically there is no way to render IR at 1/2 - 1/4 of the resolution upscaled to full size? With some proper advanced filtering, this would indeed work even better. I am already happy if I can just render at lower res but fully scaled like Adobe After Effects. This works great for IR, because you do not need quality as much as speed, and for 4K displays, things get tiny fast. (I hate upscaling windows, I am happy with 100% at 32") But for IR VFB it is a bit small.
