I also have something to add besides overall FPS drop: I run EVE in windowed mode, 1920x1080. While docked and in hangar, zoomed all the way in, FPS is 49-51, when I focus to some other application, e.g. iTunes, FPS drops down to 40. And if I scroll my playlist in iTunes, FPS drops down even more to 20

In activity monitor, it shows that EVE is using 1.07 GB Real memory, 90-100 % CPU time while in dock and 1.25 GB memory, 115% CPU in asteroid belt or mid-warp.

Confirming that this fixed it for me as well.

Confirmed higher framerate, about double. CPU usage is slightly less, about 5%.

I've got an 8 core also, but as for load balancing across CPU's, it actually does that via the kernel scheduler. Each thread has a "level" assigned to it, ranging from normal, to realtime. The only ones the cider process can use is "Normal" and "System High Priority". The other 2 are "Kernel", and "Real-Time". You CAN renice the cider application: renice -10 -p 'PID' Or -20, or whatever, just dont drop it too much or other stuff will cease working properly ;)

Also, you can't set processor affinity like you can in windows and some other unix's.

This worked for me, before doing this I was getting max 11fps. After trying this out I get stable 38-45fps which is good. I'm on a 2011 macbook.

Oh wow, disabling Multithreaded OpenGL worked for me. Now I got up to 130 FPS in windowed 1920x1080 in belt with "Optimized for performance" (Medium quality textures) and up to 105 FPS with High quality textures. CPU and memory usage has dropped to 80%/960MB.

Edit: Not sure what's changed, but with High quality textures and lots of asteroids now I got stable 130 FPS.

So it seems there are at least two separate issues at play here, one is the Multithreaded OpenGL option misbehaving and the other is a general performance decrease. The latter is not Mac specific and is being researched by our graphics experts, the former is also quite elusive since it doesn't seem to be affecting everyone but it is also being investigated by CCP and TransGaming

Thanks to everyone who posted in this thread, please continue posting here if you find any interesting data points pertaining to either of the two issues listed above.

Thanks CCP.

For me the decrease while in space is small. I was able to triple box a mining op with reasonable performance. Note that I also nerfed my own FPS in space by setting the shader to medium. I did that because when I upgraded to 10.7.3 (from 10.6.8) planets acquired white polar caps, and going from low to medium shader fixed it. (Is that a known bug? Ive heard others report it, months ago.)

The big falloff seems to be in CQ, a factor of 2 or a bit more, even with multithreaded off.

Okay, today's performance seems to be better than Tuesday. I'm getting about 20-30 FPS multiboxing missions, depending upon whether or not I'm zoomed in on a lot of Large Collidable Objects/Structures.

Transgaming have found the cause for Multithreaded OpenGL not behaving as expected (error is not in Cider though, they just pointed out what we were doing wrong) if everything goes according to plan we should have a fix deployed early next week.

Is this fix going to be in the patch that was delayed for the launcher work, our will it be included with that launcher patch?

Also, thanks ccp for picking up on this thread and fix done in a timely way!
