Title: DDRAW vs D3D Poll - Issues with cropped bezels & vector games
Post by: cmoses on April 22, 2009, 09:48:13 am
I recently had some issues with a few "higher" end games Shuffleshot and World Class Bowling Deluxe.  The games would start and then have issues, slowness, sound problems, etc.  I did some searching on here and it seems that the preference for video display mode is DDRAW.  I made the change in my mame.ini but really haven't seen a difference in performance on those games.  I am using a Wells Gardner D9200 monitor and a Nvidia graphics card, but it does not run Soft15 so I am always running at 640 x 480 resolution. 

I did notice some other things that changed when I went to DDRAW.  I was using cropped bezels on vertical games to help fill in the "black bars" on the sides.  When I switched the bezels went away.  I could only use them if I was in "Full" mode. 

I also noticed that DDRAW was not good for my vector games.  Asteroids, Asteroids Deluxe, Space Duel, etc, all started to have issues when I switched to DDRAW.  There was sound issues, pausing, stuttering, etc. 

So I have changed my mame.ini back to D3D.  I did not see any performance gains, I missed having the cropped bezels and want to play vectors.  I may change a individual game to DDRAW to test for better performance, but in general D3D seems better.  I have considered giving a ArcadeVGA card a try at some point and try running at authentic resolutions and may need to go the DDRAW route then.

Have others experienced the same issues?  What are most people using?

D3D has always given me the best results. AMD dual 2 ghz with 2 GB RAM, 19" PC CRT, and a PCI ATI card (64 MB).

What other "stuff" is running on the pc?  Anti-virus software etc?  That may have some affect on it also.  I was running a slower system across the board than yours and didn't have any issues.

Yeah, that would be an issue.  Changed it to GHz in the original post.

It is a very clean system, only have 16 processes or so running, removed all the non necessary services per a post I found on here.  No antivirus, no windows update, etc.

Any chance its all the USB devices?  I have (2) U360 joysticks, the Mini-Pac, GGG Electric Ice Trackball and Wireless Mouse/Keyboard, all of which are USB.  I wouldn't think this would be an issue.
