I have an issue, I was recently trying to see if the high poly limit of 2 mil is still an issue with 16gb of ram. Apparently it is and even when I assign realtime priority to blender in the windows 8 (ugh I know) task manager, everything runs off of my processor and it only maxes out at 3gb of ram. is there a way to increase this so that blender is using more ram and I can run more dense models? I know it’s impractical but I just want to get the best performance out of blender with what I have…
Are you running a 64 bit version of blender on a 64bit operating system?
The limit for memory usage on 32 bits is 4GB.
I was able to push blender close to the limit of my ram. It does get sluggish, but it’s functional…
What are you doing that requires so much!?
I’m running a 64 bit machine and I always make sure to use the 64 bit downloader.

How did you do this? are you running blender on a mac or windows? (looks like mac)

Nothing, at this point I’ve never needed to go past 2 mil. but blender starts to become super sluggish around 2 mil and that’s kinda annoying when I’m running a computer with blender’s best system requirements. especially considering that when I sculpt in zbrush on this machine I can get up to 6 mil.
I’m running on Linux Mint 64bit…
The OpenGL code (known to be an issue) for rendering the viewport in Blender will be causing part of the slowdown, however also depending on your GPU’s specs can affect viewport performance based on # of polygons.
I should have posted this earlier…
AMD FX-6300 six core
16GB RAM
GeForce GTX-660
So yeah… maxing out at 3 gb of ram when running 2 mil polygons really isn’t acceptable for me.
Let me clarify this a bit more: Using more RAM is not going to make Blender faster, if the whole scene (which it will be) is loaded in 3 GB of ram, than it can’t use more than that.
Things that could potentially increase your performance would be followingmib2berlin’s link, that thread does include some things that help a fair bit, depending on your setup.
Otherwise a faster CPU (for CPU limited parts of the viewport) in single threaded environments could help, either by overclocking or getting an Intel CPU (which have better single threaded performance)
