Checking if Minecraft temperatures are typical.
Checking if Minecraft temperatures are typical.
I'm running Minecraft 1.19.2 with Optifine on, building a big bamboo farm and a kelp farm that's 13x13. My temps are usually in the 40s while I idle, but now they spike to 60°C after setting up automatic farms with pistons and observers. It seems those pistons really do demand more processing power as you add more of them. I'm using an i5 4590 with 16GB RAM, a Resource pack for x32 Vanilla textures.
Experimenting with shaders? Turn them off and monitor temperatures. Lower the render and simulation distances, then observe temps. A resource pack might increase CPU usage based on its features. Generally, disable all add-ons, test vanilla settings, tweak distances, and once temps align with your comfort and game runs smoothly, enable add-ons gradually while monitoring performance and temps.
minecraft happily maintains your CPU at its highest possible speed, particularly when there’s a lot happening on the tick channel or if optimizers like optifart are interfering. (optifine isn’t as effective anymore—it’s too heavyweight.) Still, don’t stress about temperatures while playing. If you care about temps, run a CPU benchmark. 60°C is still quite cool. For tips on fine-tuning your minecraft setup (unless high FPS isn’t your goal): - Choose fabric or forge of your preference; I lean toward fabric, though many prefer it. - Add sodium (fabric) or magnesium (forge) to handle most optimizations better than optifart. - 'Entity culling' is a newer feature that omits rendering unseen objects, which can significantly improve performance with large mobs or item clusters. It’s available for both forge and fabric versions. If you’re not comfortable installing mods yourself, the Prism Launcher (https://prismlauncher.org) offers a solid, open-source option—though comparing launchers quickly becomes tricky.)
Iris/Sodium experiences performance problems, causing delays and frequent crashes. Optifine seems less ideal, though it lets shaders function properly. At least that’s the case for me.
I've had a completely different outcome. According to what I've learned, OP isn't running shaders—just OptiArt and a modified 'faithful x32' resource pack. Iris might be more stable on Fabric than it is on Forge, but I wouldn't doubt sodium problems too much, since most speedruns today rely on sodium for better performance.
Funny how things changed when I moved from Optifine to Iris/Sodium. I was using Sildur's Extreme and later had to switch after a major update. It worked well with Fabric or Forge, but I ran into Java memory issues even with 8GB and then 16GB set. It wasn’t a big problem at first, just some errors popping up.
Most recent CPUs limit heat at around 90 degrees, but my model runs an older design where the safe limit is 72 degrees, which feels a bit too high for me.
Do you have an iGPU? Optifine may not be the top choice, but it’s certainly superior to the standard version of Minecraft.
