kronovan 5 Posted September 13, 2022 The other day I watched an Optimization youtube in which the host did some ARMA3 parameter tweaking. 4 of the areas they changed were CPU count, Enabled Extra Threads, Hyperthreading and Memory allocator. My CPU count wasn't set correctly so I changed it to 4 (have an i5 6600K quad core). I also checked all 3 of the Enabled Extra Threads options for File operations, Texture loading and Geometry loading. Monitoring with HWInfo64 immediately showed my other CPU cores were being more utilized and performance marginally improved. While I know not to enable Hyperthreads as my CPU is an i5, I'm not so sure what to do about the Memory Allocator. I did try "Windows allocator (system)", but I immediately got a CTD in the Editor. I also tried JEMalloc allocator, but while it didn't crash I got some sound pops and occasional stutters. Definitely poorer performance than if it isn't enabled. That's got me wondering about the 3rd allocator option; "Intel TBB 4 allocator." Its listing in the dropdown has the text "(Default)" to the right of it. Which makes me wonder it that's the allocator that's set if no allocator in the dropdown is selected? I should probably mention that ARMA3 has been running very stable for me with no Memory allocator selected. So my question is; should I be worrying about the Memory Allocator? Does spec'ing an allocator help with performance in any way? Share this post Link to post Share on other sites
