I code therefore I am.
Here we go.. speed may be more of an issue of "FF tactics" being mostly a 2d game IE there are a lot of sprites involved. This WILL be slow. D3D glide and other accelerators really can't improve blitting 2d data to the screen much. So .. this will be slower. Impoving this would require monkeying with the DMA chain in the GPU but the programer.. and quite frankley most of the time it's really not necessaryI get full fps on those games and a bunch of others, but on Final Fantasy Tactics I consistently lose 5-10fps for some reason. I've fiddled around with the settings and tried Pete's D3D too (50-55fps) but nothing. Plus, Lewpy's performs an illegal operation on GPU init more often that not.
Bottom line is.. :bash: it will involve copying data from the virtual PSX memory into the virtual PSX display memory and copying that data to the display.. no real speed improvement to be had.
