Hi, wanted to check in since yochenhsieh originally discovered this issue with Windows 10. At the time , I had suggested using Razor and it seemed to have worked, but this was earlier last year before Windows had updated. The warp bug continues to be an issue for SFC3 and am curious to know if any progress has been made getting this issue corrected.

The laptop I'm using also uses an AMD Radeon and it is up to date with the current 20.2.1 version for my system.

Note, I am not a programmer or techie, just a modder of SFC3. If anyone does indeed find a solution please let me know so I can update with a fix and/or download link for my mods.

It's very accidental if warp is visible or not. This problem is not related to the gpu-driver but to dgVoodoo itself. Somehow in a subtle way.
dgVoodoo gets invalid vertex coordinates from the game when it's not visible, but I failed to discover the reason and no progress since then.

As far as I remember the game stores the objects data (like the meshes of the ships) in dynamically allocated structures and that's where the vertex data comes from.
I think the invalid data itself is generated when a level is loaded but I couldn't catch it.

Thanks for the reply. I'd agree something within dgVoodoo is amplifying whatever is going on with the latest update with Windows 10, as earlier last year using dgVoodoo with Windows 10 caused sporadic issues with the warp effect, but typically could be corrected using Razor Cortex. I noticed that the warp effect is completely missing since Windows 10 updated a few weeks back, but without dgVoodoo, SFCIII gets all kind of goofy.
