Right, it renders internally an image of size x 4.
Can this be user configurable x2, x4, x8? Lets test it.
This is not planned, because it is slow
I wish the new one to be at least as slow as the old one! For an intel core2duo is 3 times slower than the old "slow" one, more cores maybe reduce the slowness rate.
New one is a cpu killer for me.
Are you using the IR? I think this has then to do with another change (more responsive IR) which can be taken back/made configurable.
It has not to do with IR exclusively,
editor's "Render Preview" is equivalently slow, slow as never before (same with IR), I have to reduce quallity 100 to 30 to get about the same speed,
I dare to say it appears insanely heavy compared to the last one. Someone can use spatial oversampling=1 to get a faster environment but then there is no decent antialias, so I add spatial filter radious=0 for no antialias at all.
Nice to hear that the last one will be abandoned for a (good?) reason, but we have to speed up or config the new one to be more usable and fast
