GPU Usage don't get over ~30

[3dgr9]

Hey guys,

I have another problem with my new lite "gaming" rig.

 

System:

Ryzen 2400G

AsRock B450M Pro4

GTX 770 4Gb

16GB 3000Mhz

 

So my problem is I tested my GPU in Minecraft and with highest settings and 20 render range. But I just get like 30-40 fps (with GPU oc!!). 

 

My GPU temperatures are not getting over 37°C while full hd and CPU temps are 40°C-45°C.

 

The gpu load /usage is while gaming between 20-40%... So there is muuuuuch space for getting higher fps...

 

 

Has anyone an idea?

CPU load per core?

I will write and check when I'm home

 

But I don't think it's because of the CPU, do you?

This is a CPU bottleneck.

Minecraft is always CPU limited unless you're running super heavy shaders. That's about the fps I would expect from a 2400G, so lower your render range if you want more FPS. Even high end CPUs struggle above ~16 in Java edition.

Minecraft is very CPU heavy. Even if you would combine a 5900X with a 1660 it would still not get 100% GPU usage. If you lower your render distance to something like 8 or 10 it should become playable again. Also mods like Sodium and Starlight help out a lot.

 

With my 10400F and 5500 XT I also get 100 ish FPS with your settings and Optifine installed. With the mods and 12 render distance I get like 500.

Okay this is worth a try but even then I'm confused. I could say for sure that CPU load /usage is really not more than 50-60% D:

 

On other forums some people have the same problem like I have.

Can confirm: Both my 3700X and 5600X start to drop off fps over 16 chunks render distance. Up to 16 chunks i'm basically locked to 200 fps. Over that i steadily drop fps with each step up in render distance.

Your GPU is basically idling because it has to do next to no work to keep up with your CPU. Rendering minecraft without shaders is a trivial task for any half-modern GPU. You can be CPU limited even if it's not at 100% utilization.

 

Install the Optifine Mod and see if it changes for the better. Other than that there is nothing you can do.

That's because Minecraft isn't optimised for using multiple cores. I think it only uses 1 or 2. If it shows 100% it means it's using all cores. Try enabling every core in Afterburner and see what they are like, but I'm pretty sure you're CPU bottlenecked as a 2400G simply isn't made for 20 chunks

 

Running performance optimization mods may help for multi core usage. You can also allocate more RAM to the game which should help a litle bit (I recommend giving it 8gb)

 

I have a 10400F and 5500 XT, which is a better CPU and much better GPU, and still get 40-50fps with your settings and no mods.

Thanks for all the answers. I'm back home in 2h and will try mods like sodium, optifine, 16 chunks etc.

 

I will post my experiences later that day

I do

You have to look at the CPU usage per core. One core 100% is a cpu bottlekneck.

So guys the problem is solved finally solved

 

I have installed Optifine for 1.17.1 and turned all settings to the highest or I think in Minecraft it's called "beautiful" or something. 20 Chunks.

Antialising and anistropic filtering I have left on "zero".

 

Locked my fps to 60 (because not the best cooling and only 400w PSU, 60Hz) and voila: Stable at 60fps.

 

- CPU:

First and fourth core are between 30-50%

Second and third are 5-15%

Logical cores like 0-10%

Temps for all cores 45-50°C

 

- RAM:

~7000Mb while gaming

 

- GPU:

Usage is between 25-40%

Vram I think like 2000-3000Mb

Temps are very freakin good with 39-45°C
