Title: Tearing in PC-Engine driver
Post by: Moneyhead on May 16, 2018, 02:26:09 am

Is anybody using Groovymame for PC-Engine Emulation?

I have very bad tearing effects for all vertical scrolling games, e.g. 1943 or Galaga 88.
This only seems to happen in the PC-Engine driver "pce".

Everything is fine with the arcade or snes drivers.

I have tried to change frame_delay and vsync_offset  in pce.ini. But nothing seems to help.

Lots of views but no reply.

Is anybody using Groovymame for PC_engine?
Can you confirm if you have tearing or not?

If I remember correctly PC Engine runs in a resolution that's over 240 lines, so it sounds like your setup is having to downscale vertically.

But normally Groovmame should choose the resolution automatically.

I have a trisync-Monitor. So 2560x288 or even more is no problem.

I used to play kyukyoku tiger with groovymame
I never experienced or noticed any tearing.

Driver uses 242 vertical lines so maybe picture is shrinked into 240 lines.

I have also tried higher resolutions than 240 lines. No difference.

I will post a log on the weekend.
Though that a log might not help that much for something like tearing.

Too hard to get a log I guess.
