[Vulkan] "blocky" corrupted blocks running many games (Mslug 6, mvc2, etc) #194

Closed MagnusPrime12 closed 3 years ago

Platform / OS / Hardware: Windows 10 latest version, RX 480 8GB, Ryzen 2600, Radeon Adrenaline 21.2.3 (latest AMD driver) Flycast Version: Flycast Dojo for FightCade version : dojo-0.3.2 (settings screenshot)

Description of the Issue

Games run at full speed for me only with Vulkan. But games like MvC2 and Mslug 6 has screen corruption in form of blockiness. Mslug 6 is the worst (attached) and is unplayable. I assume many 2D games will have similar issues. But MVC2 would have lines on the characters, still playable, but annoying "blocky" lines corruption. Like missing a layer of emulation almost.

Debugging Steps Tested

I tried various settings like in the graphics areas. doesn't seem to help. Still "blocky" and "corrupted". Attached is what i have latest.
If I use OGL, everything is normal, but input lag and general lag is horrendous.

Set Texture Upscaling to 1. Only use this option after verifying that it works fine with the game.

@flyinghead , didn't work. Still had the same issue. Here is another screen shot...more obvious.

Any change when setting Transparent Sorting to Per Triangle?

MagnusPrime12 commented 3 years ago

@flyinghead , nope, still the same thing.

Can you try the latest Flycast standalone build?

I'm using an RX550 at the moment (ubuntu 20) and no issue with mslug6 or any other game.

@flyinghead Where can I find it? Not too familiar with Github in general.

@flyinghead , how very strange. I tried the latest standalone. I would check "vulcan" box, save it, close the emu. Restart it, I see vulkan still check. Then I would load any game, game would load, but I felt it was laggy...then I restart the emu and the vulkan box is unchecked...almost like it's not allow me to play with Vulkan...so strange.

@flyinghead , just reporting back. I took an older 2/18 master build (flycast-win_x64-fast-17e46a1d8f9a3c40b132280eb72abc9db4ec98fe) and that one saved vulkan settings fine. And roms runs crisp. So whatever you guys did on later builds messed up the vulkan saving/settings saving option. Please regress latest build on why settings are not being saved...

The Vulkan setting regression should be fixed in the next build: https://github.com/flyinghead/flycast/commit/ca107953fe2d4495740ac77598a60c82c7420492
