Re: DScaler 4.2.3a

This is not the issue here. DScaler supports Overlay for historical reasons and Direct3D9 surfaces. It just defaults to overlay. When set to DirectX it actually means that it uses the Direct3D9 surface and it should work fine. With the complete system freeze I suppose it is some issue with the …

Re: VGA Capture Thread

If we're only talking graphics vs text mode, how about training a neural net to detect whether it's looking at a DOS prompt? I'm thinking text mode is typically starkly contrasted with graphics, and the AI check can probably run in real time. Ok. Though, there is not "the text mode". You can train …

Re: VGA Capture Thread

In principle yes, but there are a few issues to solve: Imagine you have a nearly empty DOS text screen with just a prompt, or even just black. Then the algorithm has not much data to determine the correct number of horizontal samples. If you run the analysis algorithm permanently you could change …

Re: VGA Capture Thread

We had this discussion here as well, about e.g. distinguishing between 640x400 and 720x400. Also that basically every TFT shows 640x400 as 720x400 double sampling every ninth pixel. At the moment I'd say the best approach is, if you know which one it actually is to allow only one of it for the 400 …

Re: VGA Capture Thread

that's just par for the course with VGA capture, every resolution on every system needs it's own little adjustments... the really neat thing with using VCS for example is that you can set trigger modes to automatically select presets so it switches to the correct settings on any given resolution... …

Re: VGA Capture Thread

I found two more cards which might or might not have any potential. Anyone got experience with Epiphan DVI2PCIe? https://www.epiphan.com/wp-content/uploads/2015/06/epiphan-dvi2pcie-brochure.pdf I wrote an align and VGA bandwidth measurement tool for it in 2016: https://www.vogons.org/viewtopic.php …
