Quote:and now my question...
4x IR 0xAA
3x IR 4xAA++
If the SSAA shader was working correctly *glares directly at neobrain for awhile* the second option would be preferable for any screen resolution at or below below 1920 x 1584.
Quote:or is it possible to use 4x IR with AA?
It is possible, especially if it's MSAA. 4x IR + 4xSSAA would require a GTX 580 for most games.
Quote:can the highend models handel them and perform with 60fps??
I'm assuming by models you mean graphics cards. The answer to that depends on numerous other things. Which backend? OS? Drivers? Other settings? Which game? And so on. A high IR + 4xSSAA is do able on a high end graphics card. A high IR + 9xSSAA is pretty much impossible for most games no matter how powerful your gpu is. MSAA on the other hand has a fairly low performance hit. However the performance hit of MSAA scales with internal resolution.
*NaturalViolence does some math for fun*
Native resolution: 640 x 528
After 4 x 4 scaling: 2560 x 2112, 5,406,720 pixels
Number of samples with 8xMSAA (5,406,720 * 8) : 43,253,760 samples, each sample needs to be depth tested and so forth so that's going to take a long time, at 3 bytes per sample that's about 128MB for one framebuffer
I should point out though that the OP was talking about MSAA (although he keeps referring to it as FSAA for some reason, which is completely different) which DOES cause issues while SSAA doesn't.

....you make it sound like we were arguing (I'm assuming you're talking about me in neobrain). To my knowledge nothing we've said contradicts/disagrees with anything else. And for the record he's completely right about box filters, they're completely stupid to use in any other circumstance. SSAA uses a box filter because it's a lot faster/simpler than the alternatives yet as long as the scale is 2x2 it will yield the same exact quality as bilinear would.
