a couple of quick questions
« on: June 03, 2020, 04:50:27 am »
I've used GroovyArcade in the past with an X600 card and a Hantarex Polo/3 15Khz arcade monitor.  It worked fine. Really quick boot time, but some of the later games struggled a bit.

So a couple of questions...

1) Can someone tell me what the benefit is of using CRT Emudriver on WIndows over using GroovyArcade on linux?  I like GroovyArcade as it boots quickly and is simple to set up yet flexible to tweak.  But maybe I'm missing something if I'm not using Windows... ?

2) Looking here: http://geedorah.com/eiusdemmodi/forum/viewtopic.php?pid=333#p333 I can see that probably the best card to go with is an ATI Radeon HD 4XXX as that has been confirmed to have no low dotclock restrictions.  Is that still the case?  Ideally I'd like the most powerful card without a noisy fan, bearing in mind I am *only* connecting this up to a Hantarex Polo/3 15Khz CRT.   The most recent games I plan to play would probably be late 90s.

Thanks!

There is no one answer...

I prefer windows, other prefers linux...best card is ATI HD 5xxx, 6xxx or 7xxx for better suport of directx11.

In windows do you have alternative software (pixel art games by Gog or Steam), more emulators and backends (PCSX2 runs better with d3d11 for example), but surely linux will have other benefits.

Thanks

I should have mentioned, I'm only ever planning on running groovymame on this, but you have a point on the availability of other emulators should I change my mind later on.

Do the HD 5xxx, 6xxx and 7xxx cards have any low dotclock restrictions?

Is there an updated list of graphics cards from the link I gave above?

Cheers

The CRT Emudriver download page offers a comprehensive list of supported GPUs

http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=295

Always check the date posts have been made and edited (for instance, what you linked is from 2014), lost of things can change over time and sometimes google isn't the best at giving you the most up-to-date information. :-\

Dotclock restrictions are not relevant nowadays - everyone (should be) using super resolutions.

Primer: running a game at a super wide resolution e.g. 2560x240, integer/fractionally scaling the horizontal and integer scaling the vertical if necessary. Major benefits: everything centered and full screen width (if fractional on the horizontal for those games that don't have a horizontal resolution that's a factor of the super resolution) automatically.

Buy a 6xxx or 7xxx

Linux guy here. Using my fork of groovyarcade, you get a working CRT PC in 10 mins, 15 eventually if you USB stick and HDD are slow. The configuration is VERY easy. You can even give a try to it as a livecd. But it's stuck to GroovyMAME for now.

Thanks guys

Are the super resolutions still used/preferred on 15Khz CRT monitors?

@Substring - I agree I set up groovyarcade in minutes before, I love it.  Would it work just as well with an HD 6xxx or 7xxx series card?  (I had an X600 before)

Cheers

For Windows super resolutions are preferred (Windows is far faster mode switching when there are only a dozen modes rather than 100+). Linux it's not as clear cut, you still gain the benefits I've mentioned but there's no performance benefit when mode switching.

I'm sticking with Windows until Linux is proven to have the same or better latency for GroovyMAME.

Can you clarify what you mean by latency?  Do you mean input latency?  thanks again

Ah ok I see, so potentially another benefit for Windows over Linux.  Is this a known thing that windows has a lower latency?

Did you consider front ends as well?  I believe the available options are much more extensive on Windows..., and as mentioned other emulators like Demul, Dolphin (although does have a development version), etc.

Yeah I use attractmode on work's groovyarcade machine, pretty happy with that one :)

I read earlier that linux will always have 1 more frame of delay due to SDL, is that still true?

Groovyarcade works with any gfx card i've known of so far. You may sometimes need to set a minimum dotclock as some resolutions may not work (that's my case).

Works with older and newer AMD cards, make sure you have a real analog output

Thanks guys...

Another issue I've always had with every version of windows I've ever owned, is they always tend to break at shutdown time at some point or other, or take ages.

Have you windows groovymame users solved this issue and get both fast boot up AND consistent quick working shutdowns (e.g. from a button or switch on your cab)?

I have an exit script called from AttractMode for shutdown that copies various (new/changed) files to a USB stick (hiscores etc), and then calls shutdown -s -f -t 0

It doesn't take long to run.
