NOTE: Yes, we gonna use a 3rd party software. But it won't affect the ingame experience, we gonna cut the CPU usage of the game, "simulating" that we've an older PC (that's not a Sin, you can actually have an old PC).

FACT: Wonderland Online is a CPU Eater Game, like any other Game!! main difference is that WLO is intended to be running 24/7 and usually, in multiple instances.

Question: Why should I limit the CPU usage of the game (or any soft)?

Answer:
*Because you want to use your PC in something else (Multitasking).
*'cause your CPU is overheating and you don't want to lose it (it is not cheap).
*'cause you use a laptop and you don't want to burn out your legs.
*'cause you're AFK/Sleeping and you don't actually care about watching your char hitting a leopard, but you want to train everyday (of course).

Question: Is this legal?

Answer: Of course, you're the owner of your own PC and you can control it by using your "OS capabilities". Linux based systems can just Limit the CPU usage but Windows can't. Anyway this can be done by using the "Windows Quota", I gonna explain this.

Question: So, what can I do?

Answer: Let's go to it (remember, only use this while AFK or while "On Keyboard but browsing internet, listening to music or doing anything but manually play").

So, Windows by its own is able to "interrupt" the CPU usage for X milliseconds. The result of this is less CPU usage.

-Human explanation:
Linux: It can limit how much oxygen will you get.
Windows: It can cut off the oxygen every X milliseconds.

Same result: Less CPU usage -> software will run slower.

Question: How can I use the "Windows Quota"?

Answer: Easiest method is using the free software Battle Encoder Shirase.

Question: How?

Answer:
-Download it and extract it anywhere. Run the game, login all your accounts and put them to train (auto move, auto fight, etc).
-Now run B.E.S

-Press Target and select alogin.exe (one of them), then press Limit This.

Now your alogin.exe is on the list. Add them all.

-By using the Control button you can select how much % the CPU usage must be REDUCED.
You're not selecting the limit (Windows can't do this), you're selecting how much % should be reduced from the real number. This will never be the Real Number and it depends on your CPU (the bigger CPU you own, the less % it will need to run).

Question: So, how much % should I reduce?

Answer: Depends on your CPU (single, dual, quad core). You should increase the % little by little until you see the game is Slow as Hell but it's still automoving well.

Question: Risks?

Answer: If you decrease the usage a lot, you may lose turns 'cause the game didn't answer the petition on time. So, find the equilibrium.

Final question: Why should I do that? My PC is powerful

Answer: Sure, but if you're automoving then you don't need the Fastest Game on Earth, you just need it working. So you can use your CPU for other tasks: Another game, browsing, watching HD videos, decompressing files, encoding videos.
Or maybe you just want to sleep without the CPU cooler making NOISE !!!

Note: Linux and Mac users can just use cpulimit, I'm sure they know how.

So thanks for reading and take care of your Hardware, it's not cheap!
