Ubuntu 20.04.1 LTS and AMD + Steam/Proton

[Easy Rhino]

I am curious to know about other people's experiences with this kind of setup.

Out of the box, the AMD drivers that are loaded with the Ubuntu 20.04.1 LTS install just work. Native Linux games run on Steam great. Proton also works great. I was even able to get the XBOX One Wireless controller working.

However, I have found that proton games seem to suffer from lag and I believe it is because the AMD drivers for Linux do not allow for turning on features like Radeon AntiLag which helps keep frames in sync with this 3440x1440p 144hz monitor.

Is anyone running Ubuntu with AMD drivers and is willing to share their experience?

Have you tried oibaf drivers?

If only to rule out features like AntiLag, which i believe they don't support either.

Hrm, never heard of those drivers. I could give them a try. Unfortunately if you check out my system specs I need AntiLag due to a weak CPU. It helps loads in graphics intensive games.

Maybe it's something that has less to do with the driver and more to do with how the CPU is driven, so it might be a Windows specific thing. Try setting the CPU governor to `performance` and see where it gets you. It should make clocking up a little more aggressive and clocking down more conservative on a desktop.

Edit: As a side note, Freesync should be working if you have only one display plugged in, so that at least should be a plus.

Edit 2: You can also try installing a mainline kernel if a feature was recently added that you need. This is the one for 5.9.10.

The intention was to install different drivers to rule out your current drivers being the issue with the lag you're experiencing: if with these drivers you continue to have the lag issue, then it's not the drivers and, if you don't anymore, then it IS INDEED the drivers.

Also, @Aquinus : correct me if i'm wrong but Padoka's drivers don't support Ubuntu 20.04.1 LTS, right? @ least for now.

That's not what antilag is for, if you experience noticeable input lag it's because of something else.

Proton is emulation of the graphics API basically which means it goes through an additional software translation layer and that's likely the source of the lag. In other words, you're not really ever going to get rid of that.

Could that be due to my older CPU and the high resolution of the monitor?

Also, interestingly enough when I went from the AMD drivers provided with the Ubuntu 20.04 install to the latest version using the amdgpu-install-pro binaries Steam would no longer launch games. That probably is an unrelated issue...

I'm not sure. I didn't recall having any issues with 20.04 LTS myself, but since I got the MacBook Pro, I have to admit, I haven't turned the tower on in months. When I installed 20.04, everything just worked OOTB. I didn't need to install anything else and performance was decent on my Vega 64 to be frank, so I didn't futz with it.

Higher resolution requires more GPU power typically, not so much more CPU power. I'd imagine that the kicker is trying to get the high frame rates that your display can handle.

If you look closely in both of Padoka's drivers links, it does NOT say Ubuntu 20 support, which is why i said "don't support Ubuntu 20.04.1 LTS: @ least for now".

Oops, I meant enhanced sync, not anti-lag.

Can you post a video of the problem? Is your fps steady in the free sync range? Well first things first make sure free sync and 144 Hz are enabled...

For what it's worth, DXVK does add CPU overhead compared to running games natively in Windows, so if you're already pushing a CPU with a game in Windows, it's not going to perform better under DXVK. This is unavoidable and that is the cost that we pay to translate DX calls to Vulkan. If games native in Linux and those that don't use DXVK through Proton (like Doom 2015,) run well then I'd say that it's probably DXVK that's pushing your CPU over the edge. Maybe a couple more faster cores are in order?

Wine 6.0 RC1 is out now. Don't know what versions of wine you play with. Wine should have a stable version of dxvk already present. If not, winetricks should
have the newest version. I don't use proton, don't use steam much, so I configure my own fine wine..... Go to winehq.org and set up your own wine!
