Steve, can you try this test app with your GBS: https://www.atari-forum.com/viewtopic.p ... 63#p346163 ? IIRC, in that thread GBS was marked as one of those *not* drawing every frame.Steve wrote: 24 Feb 2022 12:10These days you can get one of those GBS scalers with GBS-CONTROL enabled which is absolutely stunning, performs on-par with expensive options like the OSSC or Retrotinks. I made my own GBS-Control. I mean, just check out that medium res quality.
EDIT: Actually, I'm not sure whether Evil's review of GBS is a positive or negative one: https://www.atari-forum.com/viewtopic.p ... 28#p346128. That YT review seems to point out quite some defects, so... for me it makes more sense to invest another 50 EUR into OSSC/RGB2HDMI for crystal-clear picture.
