9X SSAA CPU Glitch...

[darkshadw]

Hey, when I select 9X SSAA Dolphin is going down to 30% use of my CPU instead of 100% ... My video card is going crazy and is using 100%, but my CPU is only 30%...

Forgot to mention that the EFB scale is 3X .

Sorry for the rubbish English .

well, cpu is waiting for graphics to finish.

Because 4x and 9x SSAA are very intensive on the GPU, even for the most powerful cards. I'm sure I remember rodolfoosvaldobogado mentioning that 9x SSAA is very intensive and could even bring powerful graphics cards to their knees. 4x SSAA is not as bad, but tends to cause some fairly large drops. 2.5x SSAA was the best option with the least performance impact, but it seems to of been removed in the latest revisions.

very interesting... he now i am going to try 9x SSAA on an HD 4770!

2.5x SSAA was kinda glitchy at times, I'm glad it was removed

[shawnanastasio]

i am sad it was removed. i have many low-end GPU's and that was my only SSAA option..

Ooh well, you could make a patch for the 2.25X, but btw the slowdown only occurs with EFB Scale 3X selected! Probly too much to ask for my PC :p.
