Cool, I'll give it a shot a bit later. Not much to report on the WA2xSaI front, but in looking to make the code more sane so I could work on it more easily I managed to speed up the 2xSaI filter a bit. Also the WA2xSaI filter, but you still won't be able to use it

I guess one step back brings later two ahead or something.

So it would seem! I'm getting about 67fps with the 2xSaI shader on my laptop now; compare that to the 41fps I started out with!

Here are the filters you asked for:
Scale2x,
WAScale2x, (Weighed Average Scale2x)
Scale2xCR, (Scale2x with reduced colours)
WAScale2xCR.

WAScale2xCR is the slowest of the lot, getting about the same speed as WA2xSaI on my laptop.

Nice work.
Sure it will look nicer when the AWF gets improoved.

It'd certainly be slower! The Weighed Average filter (which I made up, though the concept is nothing new aside possibly from using cosine) is pretty simple right now. Any edge detection I build in is going to kill the speed.

Guest, could you try the following Fragment file? It cuts the amount of texture lookups used by a fourth, though it's a bit hackish and slower.

Btw. u could post the "clean" faster 2xSaI ver.

PS: "My" compiler seems to require "true" instead of "1"...

Heh, I guess I'm a bit bent on getting this working for everyone. Still hoping to reduce the amount of texture lookups without hackish behaviour, but I haven't got any good ideas ATM. So does this version work for you?

It produces a "very old" adapter state which i had last with my radeon 9600.
Black screen, 0.1 FPS, have to reboot to gain normal screen scrolling...but the app doesen't crash.
Sure u can do "shorter".

Merp, I was expecting something like 12 fps going by your earlier figures.. guess ATI hardware and software is really different.
