Numbskull

Thanks for your help. All the other emulators seem fine. I went with this AMD configuration based on ETAPrime's results with the same build. Always been and Intel/Nvidia user and I went out on a limb for a super compact build. I'll just keep my fingers crossed for a driver update. Any other 2200G user's experiencing this? Mobo is an MSI B450i.

Everything is running great on my original machine,building a new Ryzen 2200G mitx system. When I try to run Dreamcast or Naomi games I get weird video distortion/artifacts. I'm running Dreamcast games through ReicastOIT but have also tried Reicast, Redream and Demul. Naomi games are running in Demul. Dreamcast only renders in diagonal stripes, demul is covered in blinking pixel noise. I've reinstalled video/chipset drivers and even did a fresh windows install. Has anyone seen this before? I'm totally at loss for what could be going wrong and I think I've got a bum CPU/APU?

When I crank up Reicast's internal resolution to something like 1920x1440, it looks great, and runs great when I'm using Retroarch on its own. However if I launch the same games via Launchbox, Retroarch is crashing when using any Reicast internal resolution other that 640x480. Is there a conflicting configuration somewhere that Launchbox would care about? One that doesn't Retroarch when running independently? Update: Looks like the crashing is dependent on shaders, everything works great with no shaders enabled, once enabled starting a game from Launchbox crashes Retroarch. Update 2: Narrowed it down further to crashing only when a shader alters geometry, I can work around that but I'm still curious why this would only come into play when launching from Launchbox?
