Question / Help Laggy Computer

[Spyalex]

It may be my Laptop: MacBook Air Mid-2013, 4GB Ram, 120GB Flash Storage, OSX 10.10.9 Has Lag whenever i am streaming and playing Minecraft. My Minecraft settings are on super low, and im still lagging, and usually i only have OBS and Minecraft open, sometimes VOX but thats it :/ here are the screenshots,

There... what does the log do for anything i posted a log from today, need one from a stream?

I've had the same problem, but for league of legends, and my computer overheats as well...

try to lower fps to 30 or 24 and resolution to ~720p if problem persists to 480p

@Spyalex Do you use Optifine in your Minecraft?It helps a lot.

 

[Harold]

Except when it interferes with capture.

Its usually on 48 FPS, and my Settings are for my Monitor. Dont you think downscaling will create EXTRA lag?

 

[Spyalex]

Monitor is: 1440x900

 

[Harold]

Downscaling doesn't create lag. It's cheaper on the cpu use front to downscale than it is to encode the additional pixels you are dealing with when not downscaling.

I do, i have optifine, the settings are on SUPER low btw. also, what should my Downscale filter be?

Then what should my downscale filter be? it's at 16 right now

 

[Chidorin]

fastest with less quality should have less impact on your cpu

Yea but wouldnt Fastest-16 be bad with Minecraft, with all the Moving around and jolting?

 

[Chidorin]

the problem as I understand is "Laggy Computer" so you have to make it stable/unlaggy first and then improve the quality of the stream little by little. It's hard for me to say if your computer good enough for gaming Minecraft and streaming: "Mid 2013" seems good, but "Air" not. As I know minecraft cpu dependant and with the redline at 4-5k passmark score the core of the problem lies in slow cpu

It depends on Macs,actually.Air can be faster than Pro because it utilises SSD instead of HDD to save RAM.Also I followed this guide which helped me a lot.Just remember to set the CRF to 17.

An example of me playing Minecraft here.My specs are in my signature.

Except that HDD/SSD isn't where the bottleneck is.
The processor is.
