Launch Parameters: CPU and game optimization guide
For those that don't know, here are useful launch parameters for running the game properly. Also, some other useful things.

Use this parameter to allocate more RAM to the gamae. Fixes some crashing
-maxMem=8192 (For anyone with 8GB OR MORE)
-maxMem=6144 (For 6GB users)
-maxMem=4096 (For 4GB users)
increments of 1024 per GB to a maximum of 8192
-----------------------------------------------------------------------------------------------------------------
CPU CORES: Intel and AMD (Set the amount of cores you want to use)
AMD users
-cpuCount=2
-cpuCount=4
-cpuCount=6
-cpuCount=8

Intel users:
For non-hyperthreaded CPUs: same as AMD

FOR HYPERTHREADED CPUS WITH 4 CORES: -cpuCount=8
FOR HYPERTHREADED CPUS WITH 6 CORES: -cpuCount=12
FOR HYPERTHREADED CPUS WITH 8 CORES: -cpuCount=16
-----------------------------------------------------------------------------------------------------------------
VRAM (GPU mem allocation)
-maxVRAM=<number>
increments of 1024 per GB
-----------------------------------------------------------------------------------------------------------------
Starting your game faster:
-noSplash (Disables startup videos)
-world=empty (No world loaded at the main menu)
-----------------------------------------------------------------------------------------------------------------
example: -noSplash -cpuCount=8 -maxMem=8192
