Is this normal for a Hercules Prophet Kyro 2 board? Is it maybe something wonky with this card and my OSSC together? Or perhaps a driver setting? I don’t see the same issue in Windows, just in-game.

YouTube obscures the issue a bit, it looks like noise to me and maybe it is, just odd it would only appear in-game.

That looks like it needs a phase adjustment on the OSSC, at least AFAICT from the video .

Have you tried changing your vga cable?

All of my Kyros are pretty clean and sharp image wise, certainly nothing like your video shows.

That's across an AGP Kyro, PCI Kyro and AGP Kyro II (all Hercules).

Thanks for the replies everyone. I’ve tried a different cable and I’ve tried changing the phase settings on the OSSC. It really looks more like film grain.

Here’s another example:

YouTube does a great job of smoothing it over 🤣.

It looks like a memory issue, some sort of texture not being properly rendered / not displaying correctly....

Can you check the AGP Mode you're using? Switch to 2X and 4X and see if it makes a difference (if your motherboard supports it). Also try the card in another system possibly.

Also try another agp card in your system to rule out the rest of the pc and or monitor.

I’ll try in another system and using an actual CRT, hopefully tomorrow. I’ve tested several other AGP cards in this system without issue.

Thanks for all the recommendations, I’ll report back!

Looks like a colored rendered snow, like you see on a out of channel or disconnected analog TV.

Cheers,

Yah it almost looks intentional, was thinking maybe it was some wacky anti-aliasing or dithering algorithm that might be driver based. First Kyro card for me.

I saw a thing on the Apocalypse 3Dx back in the day that might be related, some games it would be like the tiles didn't quite meet at the edges leaving single pixel "chinks" here and there.

Tested in another machine on a CRT and it looks fine. Must be doing something weird through the OSSC or my LCD isn’t handling the signal well. I assume.
