PSX Beetle HW graphic glitches

PSX Beetle HW latest core (23/12/2018), Win7/64, AMD RX470 with latest 18.12.3 drivers

I use Vulkan.

If i set PGXP to memory+CPU in the Options, orange triangles appear at the logo screen during boot and some games exhibit strange behavior: in Castlevania Symphony of the Night the character falls through the background and in Crash Team Racing the radar dot appears at a wrong position on the screen.

Tried with native res and 2x, 4x, 8x.

If i set PGXP to memory only, everything works fine.

It looks like a rounding error…

If i set PGXP to memory only, everything works fine.

in fact, memory only is the recommended option, cpu+memory is unstable and leads to glitches.

I have the same graphics card setup as OP and this is what PSX Beetle HW looks like for me right now. Any thoughts or suggestions?

Just tried Chrono Cross with latest AMD drivers and works fine. PGXP must be set to Memory Only in the options.

(I am also using Win10 now…)

That’s what happens if you enable the core option to ‘show VRAM contents’ or something like that. It’s a debug feature. Turn it off and it’ll go back to normal.
