when I put in a ton of blocks like 200+ I get quite a bit of lag. I've got an i7-3770k with a GTX 770. I'm just wondering if other people are able to make similarly large machines without lag.

That happens to pretty much everybody. The problem seems to be mostly that the physics engine only runs on one single core at the moment. As a workaround you can try slowing down time using the slider in the upper left, that usually improves framerate.

Using the speed slider definitely works.

Using braces instead of beams, wherever possible, has given me a huge boost in performance.

That's nice, my seven cores almost never get used :/ |

I get similar results with i7 gtx750 setup
But usually only the first second of playing, then it goes back to 55+ fps usually (1280*1024, no DOF)

my machine can handle it pretty well but 300+ i start having to lower timescale.
No real frameloss when recording except at full 1440p at full timescale on large items (then it just tanks unless i timescale to like 30%)
Iv tried some stuff to try improve performance but short of multicore/thread support nothing really worked.
Xeon e3 1240 4.0ghz / 32gb 1866 / ssd / 2x r9 290 ref
as stated before it just mostly sits on one core, thou have have noticed it jump to another sometimes (might just be idling and something else is using it dunno)

if it was gpu, chances are PhysX be used, which is a Nvidia only thing. You can emulate it on amd card/intel cpu but holy hell does it s**k. If only Nvidia didnt break the "modded" drivers with their "you haz amd, no nvidia physx for u". I remember when there was a hacked driver that allowed you to have say a good amd card, and a mid range (550/650) nvidia and just have the nvidia do the physx :C

dont do nvidia settings. i run amd (although i prefer nvidia) my comp is a beast though.

All physx calculations are done on the cpu and amd/nvidia cards make no difference here. |

ah, ok. Explains the huge jump in framerate from a 4.6ghz g3258 to a 4.0 e3 1240v3. Thou it be nice if the game could somehow take advantage of higher end cards horsepower  |

Oddly enough - CPU usage goes down when there's a lot of blocks in the model. About 60% full on my machine. (60% of a single core, obviously the others aren't being used.)
It's like a glitch that stops the CPU being used nearly fully.
I hope the update to the new multi-core Unity system removes the issue entirely due to the new code base. I want to try a big model on 32 cores.
