CPU Cores Maximizer program worth for Planet Coaster

Don't buy that program. AFAIK, all it does is change some Windows settings which can easily be done by yourself. I haven't actually done it myself for PC yet (but thanks to your post you reminded me of this so will definitely try it as well), so I dont know if it works for Planet Coaster, but hey, it might be worth a shot! Here is how to do it:

  1. Run Planet Coaster (or any game you want to do this for).
  2. Open Task Manager (Ctrl-Alt-Esc).
  3. Find the game process (In tasks, right click on the game -> Go to process(or details for Windows 10)
  4. Right click on the game's process -> Set Priority -> High (DO NOT choose real time)
  5. Right click on the game's process again -> Set Affinity -> UNCHECK CPU 0.
  6. Go back to your game and hopefully you have better performance.

So what does it do? It gives the game a higher priority than other applications running on your PC (duh). The 'Set Affinity' Step basically stops the game from using core 0, which is used by the system (OS) and many programs. Because the game will run off a different core, more processing power is available for the game. Planet Coaster is ultimately bottlenecked by Single Core performance because of drawcalls. It does make great use of multiple cores (and even hyper threading!) but they will never reach 100% load (because of the main core drawcall bottleneck).

This is awesome, I will try this the next time I play! Thank you so much for taking time to write this :)

By default a process can run on any available core. That is true for system processes as well as games. The OS will schedule work across cores as it sees fit.

The Maximizer program itself locks OS processes to core 0. If you are going to set the affinity mask of the game without using the tool you will need to do that step as well.

Has anyone used the flowing program:

Is so, does it make a difference and is it worth to buy to optimize Planet Coaster?

As a note for CPUCores version on Steam... many have reported it as a "fake-application" that only does placebo effects. Technically, all it is doing is changing CPU affinity and process priority.


There is also this discussion here, which is quite recent: https://www.reddit.com/r/Steam/comments/6j8iyi/do_not_buy_cpucores_from_steam_here_is/

Within the link above, there's a free, open-code (AutoIt), alternative here: https://github.com/rcmaehl/NotCPUCores
