SDLMAME + GLSL on Linux = hardware performance

[spider75]

Hi Guys,

Sorry if this has been already debated, but I tried to search the topic and didn't find anything.

I'm building a bartop arcade cabinet (very slowly, but it's fun thing to do it with my 5yo son) and it's time to choose the hardware.

I am really thrilled by the GLSL effect so I'd like to use them. I've tried the "standard" CRT ones, and the Lottes shader (http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=330562&page=0&view=expanded&sb=5&o=&fpart=1&vc=1)

The performance on the laptop I'm using for prototyping the software are really really slow.

I was wondering which is a good combination of CPU/GPU I can use for this configuration.

I'm not planning to put PSX2 or Dolphing game on it, I'd like to stick to arcades and maybe some 8/16bit console, so I'd like to not waste money to build an overkill system, but still I'd like to play most Mame game with the GLSL shader.

At the moment I was thinking of these two configuration:

* AMD 5350 + a discreet GPU like GTX 560 which I could find used for not much money
* AMD A10 7850, which has a in-chip GPU of the R7-250 kind (more or less)

Any experience?

Thanks!

I can run the CRT shader on a radeon HD 4650, 3 ghz single core celeron D on 64 bit linux at 100% on 1280x1024 4:3 LCD panel for most non 3d games.
3-d fighters like jojo's venture ran at %80.

However, I never checked to see how it ran without the shader so it could just be the cpu wasn't up to it because it is old & weak compared to today's bargain bin CPU's.

I can confirm that most 80s classics will run with a Dell Optiplex 755 Core 2 Duo, 2.6Ghz, 4GB DDR2 with an ATI 3200(?) - post SFII fighters tend to suffer a bit on my setup, however
