Hi all, I'm going crazy trying to fix persistent stuttering in 2D browser games on my Lenovo Legion 5 Pro (Ryzen 7 5800H + RTX 3060). This happens across EVERY distro I've tried (Debian 12, Fedora 42, Mint Cinnamon, EndeavourOS, Nobara, PopOS) and EVERY browser (Firefox, Brave, Chromium).

Key symptoms:

• 2D browser games stutter badly with low framerate
• 3D WebGL browser games actually run fine (???)
• Native games run perfectly (Captain Claw via Lutris works great)
• Same exact game runs perfectly on Windows 10 on the same laptop

Someone else with an RTX 3060 tested the exact same game, seeing the same ~20W power draw, but has zero stutter issues.

Here's everything I've tried so far:

• Graphics drivers: Both nouveau and NVIDIA proprietary drivers (570.133.07), both with open and proprietary kernels
• Display settings: Tested at both 60Hz and 160Hz refresh rates
• Hardware acceleration: Enabled and disabled in all browsers
• Power modes: BIOS set to both Dynamic and Discrete graphics
• BIOS tweaks: Disabled virtualization, no power management features available in BIOS apart from that
• Performance forcing: Locked GPU clocks manually (nvidia-smi -lgc 1200,2100 and -lmc 7000,7000). Enabled persistence mode
• Added kernel parameters for power management (pcie_aspm=off acpi_osi=Linux)
• Lenovo-specific: Installed the Lenovo Legion Linux drivers from johnfanv2/LenovoLegionLinux
• NVIDIA power management: Tried enabling Nvidia dynamic boost with nvidia-powerd.service

I've monitored GPU power draw during gameplay and it hovers at 20-25W even when the light is red (performance mode) and the card is locked at P0 performance state. This is considerably lower than the ~80W it should be able to draw under load. It might not need to draw much more, but right now it's not drawing any more.

When I run the Firefox profiler to see what's happening, I can see the frame drops but there's no clear cause. And the fact that 3D browser games work fine but 2D ones stutter makes no sense to me.

Does anyone have other ideas or have you encountered this specific issue? I'm wondering if it's something specific to how 2D content is rendered in browsers on the RTX 3060 with Linux.

Thanks in advance for any help!

Hi all,

The quick and dirty questions is: Which distro should I try next?

I tried Debian X11 and Fedora with Wayland, but I did not have a great experience with them for my Lenovo Legion 5 Pro RTX3060. I installed proprietary drivers on both systems since people say that they're better than Nouveau, but the framerate stutters even in simple browser game.

I use some software to slice 3d models for printing, and that one stuttered too. I tried various fixes but none of them worked, and I'd really like to switch to Linux from Microsoft for my daily driver.

What distro can I use to have a better experience? Any advice is welcome, but please make it as specific as possible and if you can, address why that distro would be better than Debian 12 and Fedora 42.

Thanks in advance!

Hi all,

I recently installed Debian 12 on my Lenovo Legion 5 Pro, and am using the GNOME desktop (x11). From time to time I play a game called survev.io . It's a browser battle royale game, not hard on graphics.

I have an Nvidia rtx3060 and have the proper drivers installed. I checked using nvidia-smi and Firefox is using the Nvidia gpu.

The issue is that the game runs smoothly until I press a button or move the mouse. Then the framerate decreases significantly and it becomes unplayable.

I already tweaked the following settings in Firefox to no avail:

• gfx.webrender.all = True
• enabled hardware acceleration
• layers.acceleration.force-enabled = TRUE
• gfx.x11-egl.force-enabled = true

And now I'm out of ideas. The game itself isn't too important to me, but other browser games do the same, so it's a wider issue I want to solve.

Any ideas on how to resolve this?

Hi all, I'm trying to have my rpi5 running raspberry OS communicate with the Internet only through the tun0 interface (vpn). For this I wanted to create a ufw ruleset. Unfortunately, I've hit a roadblock and I can't figure out where I'm going wrong.

Can you help me discover why this ruleset doesn't allow Internet communication over tun0? When I disable ufw I can access the Internet.

The VPN connection is already established, so it should keep working, right?

I hope you can help me out!

This is the script with the ruleset: sudo ufw reset

Set default policies

sudo ufw default deny incoming

sudo ufw default deny outgoing

Allow SSH access

sudo ufw allow ssh

Allow local network traffic

sudo ufw allow from 192.168.0.0/16

sudo ufw allow out to 192.168.0.0/16

Allow traffic through VPN tunnel

sudo ufw allow in on tun0

sudo ufw allow out on tun0

Add routing between interfaces (I read its necessary, not sure why?)

sudo ufw route allow in on tun0 out on wlan0

sudo ufw route allow in on wlan0 out on tun0

sudo ufw enable
