Thats the settings I use to play Alundra. The game plays perfectly like that with absolutely no problems at all. However I want to reduce the resolution to 640x480 but when I do the game plays slightly slower than usual in full screen mode. When windowed it plays fine.

Anyone know how to fix this? Thanks

Try disabling psx aspect ratio and enabling texwin pixel shader. You should try also lowering offscreen drawing to 1 and framebuffer effects to 2.

640x480 is the best resolution for playing on a TV through TV-out right?

Well, your tv display isnt going to use anything higher than that fully, so yes, it's probably the best. It's really weird that you are having a slowdown lowering the resolution. Maybe you should try updating your card drivers, or if they are the latest, try a previous set, maybe the one you are using has a problem with that particular resolution.

Kind of off-topic, but don't most TV's run at 320X240?

No.
NTSC is ~640x480. PAL is ~800x600
There are other resoloutions, but they are on Progressive Scan capable TVs (Expensive ones.
An 'i' after the name denotes interlaced (half-height) resolution (PAL and NTSC standards are both interlaced). A 'p' denotes progressive (full-height) resolution. The name usualy shows the vertical resolution (480p is 640x480 progressive for example)
