Choppiness when playing a video

MrX_Cuci · 24 July 2013, 23:11

I tried playing a few CD32 games and i noticed that when a "video" is played CPU goes above 100%. Liberation for example is fine, but with Zool 2 (CDXL intro?) and Power Drive (CDXL intro?) it stutters like mad. Logs attached. Same problem with 2.6.1

Does it work normally if you use CD images?

I am unable to try this until Monday. I'll keep you posted.

i just tried zool 2 cd32 with winuae 2.6.1, i used cd images.
It works perfect.
could you post the config file you used for zool 2 cd32 ?

I tested it again. Works fine from image (Alcohol 52% and built-in image support), original disc stutters. If you need any additional logs let me know.

Did you test both drives? (log says you have 2 drives and 1 virtual drive)

WinUAE expects OS/drive level buffering and reads single sectors and so far it has worked fine. (Only Audio CD DA extraction uses buffering) But before implementing buffering, I'd like to confirm it is normal to have this kind of problem without buffering.. (Not sure how..)

I tried both drives with b5. Same problem although the Plextor drive seems to handel thngs a little better. Choppy audio though. winuaelog.zip
