[Tuxnes-devel] Speed?

[Jon N. <jn...@yi...>]

Reading through the archives I noticed some speed comparisons and how 
the dynamic recompilation engine basically kicks ass. At the risk of 
sounding whiny, why is it then that TuxNES under Linux is tons slower 
than my DOS version of Nesticle? (quite a bit slower than snes9x as a 
matter of fact). This isn't meant to be a complaint, more a request for 
how I can make it faster user-side, and where I should start digging 
into code for improvements on that end.

I'm running a K6-2 500, and Final Fantasy III feels subjectively slow--
pans are slow, etc. etc. It seems to be sustaining about 40 fps. Using 
the differential renderer, top reports 85% CPU in TuxNES and 15% in X. 
The standard X11-based renderer runs more of a 50/50 split.

I'm presuming, since the core engine is quite fast, that the renderer 
is the slow point here. Is this correct? And do other people sense that 
TuxNES feels slow? Would perhaps an automatic frame-skip to keep up at 
60fps help? Or is that a hidden option somewhere?
