Technical support guide

Tired of choppy gaming, bad performance, sub 10 fps in Minecraft and insisting you have a bad computer?  Well, you may have a lower end PC, but here's some tips on maximizing your current PC so you can squeeze every last bit of performance out of it!

Disclaimer - Some options are very experimental and you may cause issues to your hardware.  These will be marked with several ***.  Please follow this guide at your own risk.  Also, don't expect to go from 20fps to 60fps by changing 2-3 small

things on your computer, changes may be small, but if you follow all these steps, you will see an improvement.

Windows Upgrade

Don't listen to people.  When every new Windows is released, the previous version will always be better to them. Windows 10 Pro 64-bit is currently the fastest Windows for boot time, it has more hardware tweaks, and it supports Directx 12.0, which may not be used as often now, will likely be used more with future releases.  The home version of Windows 10 is similar to the Pro version, so if you can't spare extra money for the Pro version, don't panic, you will be fine with Home.

Power Options

Easily the first issue people who are fairly new at computers will overlook.  Don't feel bad if you missed this, it can reset if you game on a laptop and your battery gets plugged/unplugged, and I have seen pro gamers who did not know this option even existed!

Navigate to Control Panel\Hardware and Sound\Power Options and make sure to select High Performance













- Your CPU will no longer be throttled to a lower power setting, your hardware will no longer be limited by Windows.
- Everything will be noticeably faster (webpages loading, gameplay, etc)


- Your Battery will be drained much quicker if you're unplugged on a laptop
- There's some people that say this will diminish your hardware life by a small percent, but this is negligible in my opinion to the performance you gain.

Graphics Card Drivers

You would be surprised how often this is overlooked!  Every new version almost always improves performance, and in some cases older versions of graphics cards are not supported by games and you will see crashes, BSOD, or even being unable to start.

HELP!  How do I find out what my Video Card is?  Right click on My Computer or "This PC" and select Properties.  Select Device Manager on the left side of the control panel that opens and Maximize "Display Adapters"

Check weekly for updates if your computer doesn't already do this!

CPU Parking

CPU cores function like this.  Say you have 4 cores, Core 0 is used as a "baseline" and is always running at 100%.  The other cores are "sleeping" and when needed they "wake up".  There is a program that will disable the cores from sleeping so they will always be ready and won't have to pass through a "waking up" phase.  Sure, this happens so quickly, but it can prevent microstuttering and stuttering in games in general.

Right click on the program and "Run as Administrator", move the slider to full and click apply!
















***Advanced Tweaking***

Feel like doing more?  There are some advanced tweaks you can do to really push your system to the edge.  Note these options involve editing your registry, and as always any registry editing will be at your own risk!


Press the Windows Key and R and type "regedit" then press enter

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile

Right click in the window, select New > DWORD(32-bit) Value.  Name it "SystemResponsiveness" and set its hexadecimal value to 00000000.

You can also tweak the priority of games by doing the following:

Press the Windows Key and R and type "regedit" then press enter

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games

Change "GPU Priority" to Hexadecimal value of 8

Change "Priority" to Hexadecimal value of 6

Change "Scheduling Priority" to value data of High


Java Update

Minecraft runs off a program known as Java.  It's easy to use, easy to develop with, and prone to bugs.  Keeping your Java up-to-date will keep your game running, and usually every update patches some security flaw to keep your PC safe.

You also might be in the situation where you don't have the 64 bit version of Java, which would be ludicrous since you can't allocate more than 1GB ram to a 32 bit version of Java.  Should that be the case, this will help you update.

Visit the following webpage -

Ensure you download the Offline version, I find the Online version doesn't always correctly install the 64 bit version for about half the people that go through this step.

Once you download this, run it, and follow the steps.  During this update you may be asked to remove older versions of Java, click Yes to remove these versions, there's no reason to keep an outdated version on your PC.

Memory Allocation

This is going to be different for everyone in some way, and it involves a bit of general knowledge about your PC.  First, you're going to need to know how much RAM is installed in your PC.  If you do not know, right click on "My Computer" or "This PC" and select Properties.

This is what you want to record.  Once you have this, we can start figuring out how much we can dedicate to Minecraft to improve your performance.  Before we jump into memory editing, let's discuss how we decide how much memory is needed.

Generally speaking, NEVER allocate more than 12GB Ram to any instance of Minecraft, if you allocate too much memory, you will force Java to run a "Garbage Collection" too often which will cause more problems and you'll experience stuttering, lag, and choppy performance.

Minecraft modders are enthusiastic customers.  They are (usually) not game developers outside of Mod Developers, and as such are very likely to  make mistakes coding and designing their mod.  If their mod is not fully optimized and there are no errors in their code, the mod will run correctly and will play nice with Java, however this is not always the case.  Even the most well known Mod Creators constantly make mistakes.

Now that we have a Maximum number, we need to know some things about the Modpack you want to run.  What version of Minecraft is the pack running?


Is the modpack big?  Some of the bigger packs will require more RAM.  Technology heavy packs will end up stretching your computer to the limit.

You're done!  Ready to play those Modpacks!

Twitch Profile Importing:

Some of our packs are built outside of Twitch since Curse does not allow certain mods on their website, but we have exported the profiles so they are easy to download/start.

This will teach you how to import this file into your Twitch Launcher.  Begin by opening your Twitch Launcher:

Select "Mods" from the menu at the top:

Click on Minecraft, then Create Custom Profile:

Select Import (it's in purple), and select the file you downloaded (it's a .zip file):

Once you click ok, it will begin installing:

That's it!  Once it's done installing, your modpack is ready to be played!  Prefer a Video Tutotial?  Redeye has you covered:
