Devkit has a lot of seriously big problems with some small parts of it. If it were open-sourced, it would be in a much healthier state.
@Memnarch, most VMs can be configured to consume x percent of system resources for the emulation. There is probably an error in that system (i.e, it is a fixed percent as default, meaning it will allocate way over the required amount of resources) That is a typical setup for an implementation of a virtual machine.
The slowdown can be explained maybe because allocating 81% of your ram forced a lot of application memory to be paged to your (I assume SSD driver because your computer sounds pretty bad ass)
Would explain why C418 decided to go through with his 0x10c album, or he just wanted some extra $.
