New3DEngine FPS Drop

i have exactly your same card and i can confirm that triple buffering helps a lot performance wise. i tried the same settings with my old i5 2500k and HD 6670 and the difference is also huge.

Is it just me or have AMD finally fixed the Open GL problem?

Adrenalin Edition 22.7.1 Release Notes...
"OpenGL® Optimizations"

The changes were made to appease the massive Minecraft community. I was always hoping that would benefit us Supermodel users and it looks like it finally has.

Yes, I had been using the triple buffering that was recommended, but lets be honest, that was just a sticky plaster fix. Games like Sega Rally 2 were still noticeably grindy.

The latest drivers feel smooth. They are listed as 'optional', so you might need a manual update depending on your AMD settings.

That would be really great news if they did. The opengl situation on amd is bizarre. From what I recall they maintain two separate branches, one for windows and one for Linux. The windows one they only seem to care about cad compatability and performance. Where as the Linux version is optimised for games too. It makes no sense to me to have 2 completely different code bases for the same thing. But I guess they exist like this for legacy reasons.

Playing with triangles on an AMD RX580 4GB now feels pretty faultless. Sega Rally 2 no longer grinds, no more patchy slow down in Daytona 2 or Star Wars.
I can even almost play with quads now. Daytona 2 attract sequence on the old AMD driver would average 20 - 30 fps when running quads in a 496*384 window. Now it hits pretty much 60 fps solid. Quads do slow a bit when going full screen 1080, but it's a step in the right direction.
I built toxieainc's 'Faster quad rendering' GitHub branch to see if I it would improve the quads full screen 1080 performance, sadly it made no difference. It feels like the drivers are still hitting a limitation. Hopefully AMD will keep working in this direction and make further improvements.

Edit:

It seems being 'full screen' is slowing the quads down.
You can boost quad performance by running Supermodel in a window the size of your screen, just not actual -fullscreen.
Looks like the new AMD drivers are still a bit buggy.

The exclusive fullscreen also prevents fullscreen recording when capturing footage for gameplay. Workaround is to set it to "borderless fullscreen" by using your native resolution.
