Does Chankast use 3D cards?

[poison_dart3]

This is an interesting question. Chankast, one of the best emulators ever made doesen't make a difference between my old GF4MX 420 and newly bought Radeon 9600 XT 256 MB DDR RAM. Since I have upgrated my graphic card I can always feel the difference, but not in Chankast. So I ask : Does Chankast use 3D card only for rendering and everything other depends on CPU ? Because framerates on my new Radeon are exactly the same as on GF4MX, even with SH4 underclocked, although my new card is much much faster.

Chankast emulates the dreamcast GPU so any video card that is as fast and capable as the dreamcast GPU can handle it (even a GeForce 2). Of course you will need a reasonably faster video card if you want to run it at higher resolutions and use AF and AA.

I don't know if anyone else has noticed, but changing resolutions seems to have absolutely no effect on framerate at all, or at least it stays the same for me, whether i'm in 640*480 or 1280*1024.

It makes a difference if you have a GeForce 2, like me...

I think not. GF4MX cards are still much slower than new Radeons, they are close to GF2 and I was expecting a difference. But why does Chankast require a DX9 based card, if doesn't use it? Dreamcast' s graphic core was 3D acclerated after all.

It uses some of the features of DX9. If you present the graphics of a Dreamcast to a DX9 Radeon, it would laugh itself silly. However, that nasty CPU of the Dreamcast causes many more problems. Emulating the CPU is the bottleneck, NOT the graphics, same with any emulation. All a more powerful graphics card can do is play in higher resolutions and/or filtering at the same speed.

lol - just try to enable 8xFSAA at 1280x960 and you will find "some" difference in fps

Interesting point... I wonder if lowering down the effects inside the driver would have an impact into the FPSs

 

[Strange]

Heh i think its very simple:
Low resolution + high FSAA = same fps with all FSAA modes - CPU is bottleneck
Very High res. + high FSAA = big fps decrease in most of games and different fps with different resolutions and FSAA modes - depends on your video card.

In N64 emulation is the same: the GPU only makes the graphics,not "helping" to improve speed.
