HyperSpin plays fine on LCD but gets really slow on CRT?

[CanadianRyGuy]

Hi All,

Using GroovyMame and CRT-Emudriver with Hyperspin and when playing on an LCD screen, HyperSpin runs great, but then when using in my cab on the CRT everything runs very slowly (opening movie is choppy, menus are slow, etc). Is this a common issue? Should I really not be using HyperSpin on a CRT? What would be the closest alternative best suited in a cab? (TMNT 4-Player w/ 25" Monitor)

Any help is greatly appreciated as always

Not a helpful reply, but mine runs fine..

What's your PC specs?

It was a DELL computer given to me for free from about 2008, an Intel Core 2 Duo (not sure which one), 8GB of RAM, upgraded to Windows 7 myself and added an SSD. What are you running?

I should add that the emulation runs great, just the front end that is slow. I might give GameEx a try, hadn't looked at it for a while and it looks like they've got an arcade specific version now that looks quite similar to HyperSpin and can even use the same themed videos.

What graphics card are you using?

[CanadianRyGuy]

Its an HD4250, you think that might be the bottleneck?

The gfx card prob wont help the situation as thats a pretty basic gfx chip.

It may help to get a decent dedicated card which will also help if you play any heavy mame games.

The problem is the OP has probably the desktop set with intelaced mode. HD 4000 cards (actually anything pre-HD 5000) are known to have a problem with interlaced modes on Windows 7 (the refresh is halved). This will slow down anything running v-synced. Disabling desktop compositing (Aero) may help.

[CanadianRyGuy]

Awesome, thanks for the great tips! I will try disabling compositing as Calamity suggested, but will also look into a better graphics card. I had always thought that my CPU was the bottleneck in my system, but do you think a better graphics card would enable me to better play the Blitz series and other more graphic arcade games? They technically run now but are slow. I just got excited at the possibility of getting additional life out of this computer in my arcade setup!

MAME makes heavy use of GFX cards on the newer games so it will certainly play games better, not to say they will play full speed though!

You can also toggle auto frame skip to help with that situ.

MAME makes heavy use of GFX cards on the newer games

No, that's not true. Not yet. MAME's emulation doesn't benefit from GPU power. However, a powerful GPU allows MAME to use shaders for CRT emulation.

[Titchgamer]

It was my understanding that MAME somehow used the GPU along side the CPU to gain more performance.
I know that it does not support multiple cores so admittedly never really got how it worked.

What I do know is Time Crisis ran a hell of a lot better when the GFX card was changed on my machine lol

[CanadianRyGuy]

I double checked my machine and it is an Intel Core 2 Quad Q6600 CPU. What do you think kind of card would give me the greatest gains before it just becomes more than what the CPU can handle anyways?
