Hey everyone. I’m having a weird performance issue in Minecraft that persists across different Operating Systems.

My Specs:

GPU: NVIDIA RTX 4070

CPU: AMD Ryzen 5 5600

OS: Zorin OS (Previously Windows 10/11)

Launcher: Legacy Launcher

The Issue:

I’m getting very low FPS on versions 1.21.1, 1.21.10, and 1.21.11, especially with shaders. Here’s the kicker: I had the exact same low FPS on Windows. Switching to Linux (Zorin OS) didn’t change a thing.

Based on benchmarks, my RTX 4070 + R5 5600 combo should be performing at least twice as well. Since the OS change didn't help, I'm starting to suspect either a hardware issue or something fundamentally wrong with how I'm running the game.

Questions:

If the FPS is identical on both Windows and Linux, could this be a hardware bottleneck or a BIOS setting (like XMP/DOCP or PCIe speed)?

Could the Legacy Launcher be the culprit on both systems?

How can I properly stress-test my Ryzen 5 5600 on Zorin OS to see if it's underperforming or if I've been sold a "fake" chip?

Are there any specific NVIDIA/Java tweaks that I might be missing on both platforms?

I really want to get the performance I paid for. Any help would be huge!

Hi everyone,

I've recently switched to Zorin OS and I’m looking for some help to properly set up my system for gaming. I have an NVIDIA RTX 4070, but I'm struggling with a few things:

Drivers & Hardware: I need help ensuring my GPU drivers are correctly installed and optimized. Also, my microphone isn't working properly (driver issue, most likely). What is the best way to handle these on Zorin?

Running Windows Games: I am trying to run games (EXE files) directly from my Windows NTFS partition without reinstalling them. Some games give me a "No graphics card detected" error. Is there a specific way to mount the partition or configure permissions to make this work smoothly?

Proton & DLSS: I am using PortProton, but I want to make sure I have access to all RTX 40-series features, specifically DLSS, Ray Tracing, and Frame Generation. Which Proton version (GE-Proton or others) and environment variables are best for this?

Alternatives: Are there better alternatives to PortProton for my use case (running games from a Windows drive), or is it the best choice?

Saves: I’ve already manually moved my saves to the Wine prefixes, so that part is covered.

My goal is to have a "no-reinstall" gaming setup where I can just launch my existing library with maximum performance.

Thanks in advance for any advice!
