Broken emulation and unable to load games properly #1083

Closed afjara closed 2 years ago

afjara commented 3 years ago

Hi, today I launched Virtua Tennis 2 and noticed several rendering problems, especially offset screen issues. Also, when closing content and tried to launch another game, emulation starts with speed issues, like 1.5x emulation speed or freezing wheen booting the BIOS logo.

Haven't experienced this issues before, tried an april build and the same problems appears, maybe related to newer versions of RetroArch or nvidia driver issues.

Tried nigthly as suggested by #1085 and 1.9.4. Still no luck. Unable to change games.

Solved by switching to flyinghead's build.
