Using GroovyMame with Non-Arcade monitors

[8BitMonk]

I've been happily using Groovymame with my arcade monitor and am now working on a project where I'm going to be using some Dell Ultrasharp 1908FP's. I understand there are still some benefits to using Groovymame with a standard LCD like this and I have a couple questions:

• What are the specific benefits? No timing issues, sound glitches, stuttering, etc?
• What are the installation procedures
• Can it be used alongside HLSL

Is it just a matter of using Groovymame and the LCD monitor preset? Any other special settings and does the graphics card type matter? My guess would be no since you're only using Groovymame and not CRTEmudriver but I'd like to know for sure.

Appreciate any help and info!

Hi 8BitMonk,

Basically, set "monitor lcd", "aspect 16:10" (or 16:9 or whatever), and play with "syncrefresh_tolerance" to decide how big the refresh difference needs to be in order to automatically turn off syncrefresh and enable triplebuffer instead. For the later, make sure that multithreading is enabled, otherwise it won't work.

The benefits are smooth scrolling and sound synchronization. It can be used with HLSL, of course, but you'll need a pretty decent card to get good performance with it.

If the monitor is old enough there's a not so remote probability that it accepts custom refresh rates. If this is the case you might want to use GroovyMAME to interface with Powerstrip to achieve custom timings (for refresh rates different than 60 Hz). Though a card that's old enough to be supported by Powerstrip won't be good for HLSL.

Thanks Calamity! That's exactly what I needed to know.
