I hope you don't mind me picking at your guys brains some more. Got a few more questions.
So I take it OGL2Size OGL2Param & OGL2Texture are specific to Pete's GPU. What do they mean, and Are there any others? Also is there a way to see the value of those?

SimoneT - Thanx for the great links. Finally an explination of what some of the commands do, but at the same time I'm getting more confused by the moment. lol The one link with the PDFs you posted was all I could find googling. =P Hopefully I'll have some sort of shader here soon to post. =)

guest.r - Thanx for your responses, and great shaders. I'm glad you're still actively updating them.
After some more value tinkering I understand what I effected causing an interesting result in your 4xGLSLHqFilter - Full shader.

Here's the new tweaked values:
float x = (OGL2Size.x/2240.0)*OGL2Param.x;
float y = (OGL2Size.y/1240.0)*OGL2Param.y;

Everything lines up correctly now when the fullscreen filter is enabled in many different screen modes, and this allows Shader level: "4:Maximum" to produce a better quality image.

The down side is 1280x960 no longer lines up when the fullscreen filter is disabled, but if you want add a fullscreen filter friendly version of your shader then try it out & see if I'm crazy or not. ;P

Lata.
