Gpu Usage Maxes Out On An Minecraft Modpack

[Vod]

Hello!

So I built a new pc a month ago, and I downloaded a few modpacks (sevtech ages, all the mods3) using twitch.

On my old pc the same modpacks I tried to run ran fine with ~60 fps.

And back then I had a really ban pc (ahtlon x4 845, 6gb ddr3, gtx 750ti) but now with my new pc (rx 580 4gb, ryzen 5 2400g, 8gb ddr4 3200mhz) the modpacks would run ~5 fps at the lowest in game settings I could do.

I looked in task manager while I ran one of the modpacks and the gpu was maxing out at 99% while the cpu was at 30% and memory at 70%.

I thought it was a bug in the drivers or some kind of compatibility issues.

I'm gonna go try download modpacks on another modpack downaloader and see if the issue resolves.

 

Thanks!

Are you using the iGPU?

mods on minecraft are pretty notorious for being badly optimised, but it's weird that your gpu is being taxed, usually it's the ram or cpu. can you follow these steps to monitor hardware usage in game? maybe task manager is reading hardware usage wrongly

i already have msi afterburner, I'll try that now, but I don't know if I have to close the game for the gpu, cpu  usage and other to show up, if I do have to close the game it will take a couple of minutes

Edit:
Ram usage was a bit higher because I had chrome and and other programes opened

Before I would the modpack would run at 40-70 fps, the modpack is called SevTech ages

Well considering the modpack is huge, i think 100% gpu usage isn't really out of the question. I remember running a few heavy-ish modpacks with my 1070 and was getting 70-80% load consistently.

I don't think that's the problem, because on my older pc, witch had an gtx 750ti, the modpack used around 70% of the gpu

It might have been because your athlon x4 845 was bottlenecking the system. according to hypixel, minecraft only uses 1-2 cores(depending on what mods etc). and an athlon x4 845 has really really bad single core performance, so it would have bottlenecked a 750ti.

Have you tried giving MC more ram? On heavy mod packs i had really bad fps, if i didn't give minecraft 2-4gb of ram, and on your screenshot it seems to use the default 1gb of it.

I downloaded another launcher and ran the same modpack and now it's running smoothly with the gpu usage at around 40 percent

just curious, which launcher was it that you were using and what launcher are you using now?

Do you think it's possible that your previous launcher had something like a crypto miner built-in, which used up the GPU?
Which launcher were you using and what are you using now?

I used twitch, in the mods section, so it wasn't a crypto mining thing, I switched to ATlauncher. Sorry for such a late reply
