Poor performance with AMD GPU/Driver on Linux

[GotGuffz]

Describe the bug
Using the 117HD plugin with an AMD RX6800, I'm only able to max out FPS around 60 on low settings with big dips into the 20's in areas like fossil island during birdhouse runs. I recently upgraded from a GTX2060 which had no issues hitting 144 FPS stable on higher settings with occasional dips into the 110-120 fps range doing the same activities. My best guess is that there is a driver issue causing this drop in performance.

Expected behavior
With a big gpu upgrade, i should be able to easily meet or exceed the stable 144fps mark that my old graphics card was able to handle with equivalent or better settings.

Environment (please complete the following information):

• OS: Nobara Linux 36 (Fedora) KDE Plasma
• Kernel 5.18.13-201.fsync.fc36.x86_64
• DE: Plasma 5.25.3
• CPU: Intel i7-9700k @ 4.900GHz
• GPU: AMD ATI Radeon RX 6800
• Driver: Mesa 22.2.0-devel
• Memory: 32GB DDR4 @ 3200
• RuneLite version: x64 AppImage downloaded from runelite.net

Additional context
When moving from the nvidia gpu to the amd gpu, I did a fresh install of my distro. No other hardware changes have been made.
When using the gpu plugin on runelite, my fps is stable at 144fps using the AMD gpu.

What resolution is this at, 1080p? You seem to be getting much worse performance than I got on my old PC with a GTX 1070 and i7 5960x (I got like, 70 FPS max on highest settings). My current PC has a RTX 3070 Ti with a R9 5900X and I'm only getting about 90-110 FPS at 1080p highest settings in high population world GE. All of this on Ubuntu 22.04, of course.

Even more interestingly, my FPS is not stable at 144 FPS using the GPU plugin, it's all over the place from 130 to 156 lol - at least with VSync off, with it on, it's all over the place from 130 to 144.

Supposedly everything was the same, except for the GPU upgrade, which is really weird.

Different driver, that's one of the most important factors in performance. Some of them give severalfold better or worse performance either on the CPU or (rarely, but seems to be the case with linux) the GPU.

@GotGuffz
Are you still having issues with the latest release?

[aHooder]

@GotGuffz one guy in RuneLite's Discord supposedly found that AMD proprietary drivers performed a lot better with RuneLite's GPU plugin. Could you check if it helps for you as well? All he supposedly did was install those drivers and launch RuneLite with progl.

OpenAMD drivers with a Vega 56 on Ubuntu 22.04 gave me 60fps with everything maxed except draw distance (42), Shadows (4096) and MSAA (4x)

Will do a full comparison later and include mesa driver version

OS: Ubuntu 22.04
Driver: Mesa-22.0.5
GPU: AMD Vega 56
Running with settings:

Setting			High
Draw Distance			60
AA			4x
UI Scaling			TRUE
AF			16
Dynamic Lights			50
Projectile Lights			TRUE
NPC Lights			TRUE
Atmos Lights			TRUE
Shadows			TRUE
Shadow Quality			4096
Shadow Distance			70
Expand Shadow Draw			TRUE
Texture Resolution			256

Unfortunately i cannot test the AMD Pro drivers as they appear to be broken

I did end up testing the broken AMD drivers; currently unstable on Ubuntu 22.04 until AMD fixes their script (or i fix it i guess..)
In my testing there was nearly a 30% - 50% performance jump depending on the area. (Some areas are even a straight double)

Can confirm we perform poorly only open Mesa and better on AMD proprietary drivers; How much of that is us versus driver optimization is beyond my knowledge. But i'd consider this issue closed.

Can you check whether this is still an issue with Mesa 23? It reportedly may have fixed the issue: runelite/runelite#16354 (comment)

I've had ongoing issues with the GPU plugin so I suspect this is more of an issue with RuneLite rather than this HD plugin.
I've just posted an update to that issue runelite/runelite#16354 (comment) noting that it is still an issue on Mesa 23.2.
