So I'm trying to find optimal video settings for MAME but I seem to be hitting weird hiccups and I'm not sure if it's a MAME issue or a hardware/software issue on my end.
I'm running Windows 10 x64 with a AMD R9 Fury GPU and the latest Catalyst drivers on a 1080p 60hz display and using MAME 0.224 and 0.225 (results are the same on both).
The problem I have is that D3D works great except the video mixing on Laser Disc games (e.g., Cube Quest) is majorly borked and there seems to be some sort of persistence issue with the actual game graphics and they're just overlaying the previous frame instead of clearing and drawing a new, clean frame. BGFX seems just a borked, just slightly differently. BGFX also doesn't seem to respect prescale like D3D does.
OpenGL mixes the Laser Disc and game graphics fine in Cube Quest and OpenGL respects prescale, but OpenGL does not seem to respect Wait VSync nor Refresh Speed so scrolling games are a choppy mess and > 60hz refresh rate games like Donkey Kong are an audio pop and click fest. I can force VSync in the Catalyst drivers, but being that Refresh Speed isn't respected, Donkey Kong still pops and clicks.
I remember this all used to work fine, but my setup has changed over time and MAME has changed over time so I just wanted to try to feel things out here before I log a MAMETesters entry.
Anyone else experiencing the same things?
And, I know... I know..., if I got a FreeSync monitor of any decent quality, I probably could leave these sync and framerate issues, behind, but being that I'm stuck with a good ol' 60hz 1080p display, the hardware I got is the hardware I got.
Any thoughts on these issues would be appreciated.
