performance problem

Hi, at first I just wanted to come to the forums to say thanks for the project... well thanks for the emulator [img]<fileStore.core_Emoticons>/emoticons/smile.png[/img]/emoticons/smile@2x.png 2x" width="20" height="20" />

Â

But I'm having a problem with the performance when I'm running a gba game. The problem is that when I start the game runs incredible well, WAY better than the other version of VBA, but after 5 or 10 minutes the fps start to lower until it becomes unplayable. The most tests I did were with FFVI, after it became unplayable if i saved, closed the window wait a while then played again everything went back to normality until the problem began once more...

Â

I don't know if its a coincidence, a common problem or its something with my cpu, video card or memory, but something similar shows with games like oblivion or nwn2, but until now i just assumed that it was because my pc wasn't powerful enough for those games, but I just find it odd that the same thing happen with VBA, as far as I remember even with an old pc it ran OK.

Â

Well, my pc is:

P4 3,2Ghz (HT)

1,5GB RAM

7600gt (AGP)

Â

I hope you can help me, if not then thanks again for the effort of developing this

Use OpenGL for the video mode, and make sure Antialiasing is disabled.

Â

Use OpenAL or Xaudio for sound output.

..That is odd [img]<fileStore.core_Emoticons>/emoticons/unsure.png[/img]/emoticons/unsure@2x.png 2x" width="20" height="20" />. I never had that issue during development. I'll try to get some time to test it out for myself to see if it is a real bug....

currently playing FFVI on a lesser system with no performance issues.

I believe I have witnessed this, with several games, to a lesser extent: VBAM reported speed at cca 50% (cca 80% with turbo) , I savestated, exited, ran (with exactly the same commandline and configuration and applications (not) running) VBAM again, loaded state, had cca 90% (₁₅₀% with turbo).

Subjectively, the games were then really a bit faster.

Â

Linux, SDL port, "stretch x1" filter (with opengl), revision circa 453.

Â

It was after couple dozen of hours of playing, plus many dozen hours of keeping the process stopped (^Z on the terminal).

I tried with Open GL but the problem is still there and i always use OpenAl

Â

I kept testing and with other versions of VBA the problem is worst!! so I'm starting to guess that is problem of MY pc.

Â

Thanks to all again

Your cpu uses Hyperthreading, try changing the CPU Affinity to only use the real core (Set Affinity to 0) in the task manager, for the VisualBoyAdvance.exe

how about me sir? i have a p3 650 mhz / 128mb laptop?

Â

i run the basic vba with no problems... with some crappy speed with other games (pokemon emerald)

Â

does my pc support VBA-M? i cant try it now because im trying to fix "D3dx9_32.dll Not Found" Error

Â

thx 4 the support!

Â

either google the dll or download the DirectX webupdater.

Â

I wish I still had my P3 to try...I never had any problems whatsoever with any games back when I still had my P3 with basic VBA...then again that was without filters and usually no more zooming that 3x...and usually playing the game at 1x or 2x.

it is safe to assume that VBA-M will likely end up with higher cpu requirements then VBA.
