Re: VGA Capture Thread

Use this utility to test the visionrgb's capture fps with whatever resolution it's tuned to: http://personal.inet.fi/muoti/eimuoti/vrgb_fps/vrgb_fps.zip Run with 'vrgb_fps.exe 0 32' from the command line (give the last argument as 16 for 16-bit color rather than 24-bit). Tells you the number of …

The manual probably says lots. The card pushes the 70 fps of vga 13h and 60 fps at 640x480, but at higher res you probably take a hit. I run it in odd ways that limit performance for other reasons, so can't say for sure. I use a custom program - what's wrong with the card's own viewer's format? It …

Bios capture with the visionrgb-pro2: https://www.youtube.com/watch?v=x033S3s8qQA The regular pro's going for $30 shipped on ebay for yanks. I still see blurry capture in new videos on youtube - doesn't need to be, not for $$ anyway, unless you're outside the us or do obscure stuff. I wouldn't get …

Re: DOS path tracing CPU benchmark

I originally wrote the path tracer core here for the game boy advance (it was slow), so the 386 is in a sense still pulling in screaming figures. Even if you converted to fixed-point, though, I'm not sure how capable e.g. a 386 would be for path tracing, in particular. The path tracer here, as …

Some further observations along those above. - d3d doesn't always repaint after portions of the pcem window have gotten clipped by other windows, need to either give mouse lock or toggle to ddraw and back to get the screen to clear - mouse lock doesn't prevent certain ubuntu (mate) hotkey …

I tested the v12 release in wine, and found that while the shipped exe crashes immediately, a simple recompile with mingw 5.3.0 without changes produces an exe that runs fine. This of course implies the same for v11, though doesn't necessarily mean it's the toolchain. With basic testing in dos, the …

Thanks for the clarification. I should also specify for clarity that the modified v11 here isn't based on the release but on an interim version off the repository from around october last year. I'm fairly sure however that I removed the videomemory flag off the release version source as well, and …

My observations of running pcem for win v11 in wine 1.6.2 on ubuntu 16.04. See reference video there. If legally possible, obtain a local copy of the video for continued access. https://www.youtube.com/watch?v=K4KvWN6Ov1s Immediate issues: - release version crashes, modified version runs - …

Last year, I tried to run pcem v11 for windows in virtualbox (linux host, windows guest), and it crashed on launch. This was easily fixed in the pcem source by removing an initialization flag off a pixel buffer. The details escape me now, and in any case I don't know the implications of this fix for …
