Please make the support of multicore processors.

Its a realy nice game. i have played it a lot and will buy it as soon as it will be available on steam. But what is realy disapoinded me is that this game has no normal multicore processors support .So with big ships game began to lag as hell even on 1/4 speed while the processor(i7-7700HQ) has only 20-25% workload. so only 1 core is loaded while 3 other doing nothing.

Mangus yeah, it is some what frustrating

It's not all on one core but the physics are, which takes up most of the processing power.

While it's not true that Cosmoteer has no multi-core support (particles, thrusters, crew, and weapon targeting all run multi-core), it is certainly true that the multi-core support is limited, both in that only those features can run on multiple cores and in that a single ship will only run on a single core, meaning there needs to be multiple ships in the game to take advantage of it.

Physics is the biggest CPU-hog that doesn't yet have multi-core support. I might look into adding it, but physics actually has much bigger problems then lack of multi-core support in that the physics engine I'm using is not designed to be efficient for games like Cosmoteer that have relatively few but extremely complex physics objects (massive ships). While adding mult-core support to physics could probably get a 2-3x improvement, fixing those inefficiencies could probably get a 10x improvement.

just in case it will help. i made some performance tests on my laptop with i7-7700hq and here what i had found.

First of all this CPU has 4 cores. if we enable the Hyper-Threading optin then we will see 8 logical processors.
in this case 2 diferent logical processor are processed by 1 phisical. so if we have 2 ships that run all phisics calculation each in its own logical processor the workload will be only on 1 phisical CPU. and overal only 25% of max performance of the CPU.

So after i just disabeld Hyper-Threading in BIOS of the system so 1 processor will be 1 logical processor.

The total workload of CPU rise to 50 % with any big ships. The performance tests shows that 1 batlle that was reproduced several times for each case with Hyper-Threading and without takes diferent time.

the results. without Hyper-Threading the overal performance rise for 35-40%

my suggestion is to add some code that will chosee diferent processors(logical or phisical) for example for frist thread select processor 1(or first) for next thread lunch on processor last(the max numbre of processors)

Also we can just set manualy in TaskManager the affinity of processor to the cosmoteer.exe thread to 0-2-4-6(with hyperthred enabled) logical processors and have the same results like the hyperthreding is off
