2D vs. 3D rendering

I've been wondering for a while now why ePSXe runs 2D games (final fantasy 6, for example) so much slower than 3d games (final fantasy 7 battles for example). I'm able to get 300+ FPS in games like FF7, but barely creak along at 70 FPS in FF6. Is this a problem on my end, or is it the emulator/plugins at fault?

Petes (D3D, OGL, OGL2)

Because that are 3D accelerated plugins, and use 3D APIs to draw the graphics. In fact, that's a question you should address to ATI, as they are the ones that design the card with 3D in mind. Nowadays, graphic cards are focused mainly to move zillions of polygons and apply tons of fancy lightning effects on them, so it's no wonder 3D is much faster than 2D. You might want to try PEOPS spu plugin, as it's a directdraw plugin, and is faster when using 2D.

GPU not SPU plugin.

Software doesn't run faster, but the overall performance and graphics quality is much improved.

Performance? I think that the software rendering is relying on the CPU power and is not dependent on the video card.

software can be faster, depending on your CPU/gfx card. if you have an athlon64 and a GF2mx, then software plugins are going to be a bit faster

There were some slowdown issues in the menus that were gone, along with some wierd menu rendering giltches (menu options diappearing and becoming scrambled). There are no more slowdowns, and the filtering in PEOPS smooths out the graphics better than OGL2 did.

P.E.Op.S. is generally recommended for 2D games anyways
