Q/A about Graphics and FPS

[jedikevin20]

Being Serious but your specs are not the best for dolphin. Take it from a person who use to have a Pent D. It SUCKS. Its a duel core but its not really. Its a really bad Intel mistake and that in itself its hurting you badly. That is probably your most limiting factor. Also dolphin fluctuates in speed depending on game and your PC specs. What works well for some people will not for others. Just something to keep in mind.

Next, I've personally never heard of "4253-x86-1GBhack one."
You should head over to this forum section and pick up a version if you don't want to compile a svn version.

If you click Orleans build he has some of the suggestions to improve fps a bit for you so read up. (explorer.bat, gamebooster, shutting down extra processes, etc.)
As to your GPU I'm not that knowledgeable on older ATI gpu's but I'm thinking your card is ok. If you wanna fix errors, I would read through the game forum on games you have and see what others have said. That being said, games and options can tend to work fine on one version of dolphin but not on others.

To answer your last question Pal runs at 50 fps while NTSC runs as 60 nominally (couple games actually run at 30 fps like the GC game P.N.03)
