And, to backup the belief that GBS w/ GBS-Control CFW is indeed a low-lag solution and fast deinterlacer, I thought I'd do some lag testing. I think I've sampled enough comparisons here to definitely say that the processing time of the GBS w/ GBS-Control CFW is on par with the OSSC.

Lastly, GBS-8200 CFW output set to 640x480 mode (supported resolution for SM930b). The same process chain as immediately above, but with the 480p line doubling and upsample2x enabled at the OSSC. No verifiable difference:
