@AndersHP it's only slower if the shader causes you to lose frames, but i would guess that the 10% of games that you're losing frames with the crt-pi shader now, it will be less than 10% with the zfast-crt shader.. maybe 0% :)
@darksavior I did and it seems like it worked. My go-to point for latency testing has always been Batrider though, and this surely plays slower (=input laggier) than it did before. But I have not tried updating MAME2003 from source, will do this soon.
Maybe Batrider is generally just a game that's on the limit of the pi.. I tested a bunch of shooters and fighters yesterday and they all seem fine now.
You really should use FBA for certain Toaplan and Eighting / Raizing games, firstly due to the performance being better and with regards to
some games the Emulation of the sound and music is 100%............
I use FBA for all these for the above reasons
Armed Police Batrider
Ghox (Next FBA release will have sound)
