Increase Modded Minecraft FPS

Hello everyone this is dial 20 and welcome to a quick video unlike the ones that I usually do or I talked to you guys about a little nifty trick that I’ve recently discovered in Minecraft and that is how to potentially increase your frame rate or your fps in modded

Minecraft and I’m going to show you first off the setting and then we’re gonna go into what this setting is and how it works so to turn this setting on it’s really actually pretty simple if you’re playing modded minecraft you open up your mod options you find minecraft

Forge and your mods lifts you hit config client settings force threaded chunk rendering set this to true that’s the end of the story now before you go ahead and do this I should note that some older machines may not see an improvement and this can have some

Visual glittery like it might have some weird visual artifacting but it wouldn’t be too common now how does this improve your framerate let’s take a look let’s set it back to false which is the default setting by the way and let’s see what happens if I bring up the f3 manual

You notice that I’m particularly looking at my area over here and if you keep a look at my FPS you’ll notice that it spikes pretty much anything or any time something changes in the chunk in front of me and you can see that in the graph

On the bottom see those FPS spikes that are happening right there goes a little bit crazy right what is causing this and why let’s take a look one of the things that typically affects your FPS in modded minecraft is chunk re-rendering basically when something changes inside

A chunk and remember a chunk is a 16 by 16 area that you can visualize by saying f3 G and you can see the chunk borders visualized here any time something changes in a chunk be it liquid being picked up or redraw or usually redstone changes chunks have to redraw themselves

So what happens is your computer needs to redraw everything in that chunk and remember that chunk goes from bedrock all the way up to the ceiling of the world so you’re gonna have a lot of chunk redraws one way to visualize what’s causing chunk redraws is by using

The sampler mod from player and what we can do is use a can command called C sampler render updates show and what will happen is anytime a block causes a chunk rerender it will be highlighted in red so you can see that pressure plate back there is causing the

Chunk to rerender the liquid being placed and then picked back up by my droppers and sometimes items dropped me into them which cause the the liquid there to change can also cause chunk redraws and pretty much every time this happens the entire chunk needs to be reloaded by turning on the setting that

We just demonstrated it helps to offload that chunk we rendering into a separate processor thread in Minecraft basically if you have a single processor CPU this won’t help but most computers these days are multi processors so therefore can be multi-threaded if we want to exacerbate this problem we can get a redstone timer

Redstone usually causes chunk updates as well and by using a redstone pulse we can more accurately see how much damage chunk we rendering can do to your FPS now it should be noted that chunk redraws aren’t exclusive to mod ‘minecraft machines placing a block in the world causes a chunk redraw we can

See that because of the red outline there as those breaking it pretty much any time something changes in a chunk it’s going to redraw that chunk and that’s normal and that’s usually not a big deal in vanilla minecraft because you don’t have a lot of automated machines that are causing a lot of

Chunky jaws however if you build a really rapid firing vanilla of redstone clock that you know fires redstone pulses frequently you could cause this problem in vanilla it just tends to happen more in modded minecraft because we have all these awesome machines that are doing crazy automated things I’ve

Gone ahead and got myself a timer from dark utilities and we’re gonna place it right here in this chunk just to demonstrate how this can be bad if you’ve got a lot of chunk redraws so see I have a steady you know 60 FPS right now I’m gonna go ahead and place this

Here and we’re going to set this to a 5 tick delay meaning it’ll pulse 4 times a second watch my FPS notice all that staggering that’s bad now let’s go ahead and turn on that awesome setting that I just demonstrated in the mod options mod options minecraft forge config client settings true

Done and done nice and smooth no more fluctuating framerate now again this works because it’s offloading those chunk rear Enders into a separate thread on your CPU again if you have a single threaded CPU it may not improve anything and it may also cause some visual glitches which if it

Does or if it causes problems or if anything goes wrong simply go into mod options minecraft forge config client settings and set it back to false done done and done yes you’ll have you know some framerate dip again but that’s okay because you know you

Turned it off for a reason right so the urge to create a clickbait title for this video was strong but I promised myself I’ll never use clickbait thread titles or video titles so that’s not gonna happen but definitely wanted to let you guys know about this I’ve recently discovered

This CPW turned me on to this setting again keep in mind it’s not on by default for a reason so turn it on see if you have any negative visual effects and if it does cause like weird artifacting visual stuff in your world it shouldn’t break anything in your

World it’s all client-side so it won’t break your world in any way all it’ll do is potentially cause some you know visual glitches I haven’t seen any yet one thing that CPW mentioned is it can sometimes cause like World holes which you guys might remember from previous versions of Minecraft where you know

Like a whole chunk would be missing right and it’s usually like a temporary thing it corrects itself pretty quickly and it’s just a visual bug so that can occasionally be caused by the setting being turned on it’s particularly noticeable when you quarry on a chunk boundary is what cbw said so try turning

It on see if you get an FPS increase if you do cool and if it causes problems or if it doesn’t cause an FPS increase go ahead and turn it back off it’s no big deal for now dad when you’re setting off take it easy
