Vertical games in horizontal resolution

[Cisek]

Hi

My groovymame ini is set to horizontal mode, so all verical games are displayed in 4:3 ratio horizontally.
My problem is sound stuttering. When I play those vertical games in horizontally rotated mode, in a lot of games the sound is crackling.
It doesn't happen howerver if I rotate those games to their original vertical orientation.

So is there any possibility to play smoothly vertical games in horizontal irentation with groovymame?

You need to provide more information about your hardware specs, what type of monitor, and which versions of GroovyMAME and CRT_EmuDriver you are using.

Also provide a log file from when the problem is happening.
