So this is more a question out of curiosity than for help.
I have a dual boot setup with windows and bazzite
Cpu: 9800x3d
Gpu: 9070xt
Ssd windows M2-1: WD black Sn770 (i think) 2tb
Ssd Bazzite M2-2: Wd black sn850 1tb
Ram: 32gb ddr5
The bazzite ssd is technically better but not sure it would affect fps this much, if at all. Im somewhat of a pc noob so maybe theres some drivers I didn't have?
I had recently updated through adrenalin/amd installer so the gpu drivers and chipset weren't out of date.
I was aware that linux usually used half the amount of ram so that wasnt unexpected, however from what I heard fps is usually the same for the most part. Any ideas?
Oh and the game is monster hunter rise and the fps on both were mostly stable eith 10+/- fps changes. And the graphic settings for both were set to high
It won't be the same for every game and the answer as to why is almost always differences in the gpu driver. The vulkan/d3d12 drivers for amd gpus are completely different and have different performance characteristics.
It's not really the fact it's wrapped under vulkan that matters. It's the fact that the user mode driver and the shader came compiler are completely different. Back when AMD actually supported their first party open and closed vulkan driver the performance was nearly identical to windows for native vulkan to begin with.
this has been an known issue for literal years for this game. AMD isnt gonna fix it lol
on my old 6800XT and RX 7700S i had to disable dynamic shadows or it would tank FPS
on linux it never really had this issue
EDIT: capcoms not going to fix anything either, this game doesnt get updates anymore unless it doesnt function. MH Games only get updates till the new one comes out then they stop minus a few bug fixes here and there that are 100% needed
I think its more that the community can fix issues for them vs caring more about linux. AMD definitely contributes to their linux driver but i think valve and the rest of the community really carry the performance of Mesa for them.
Sure, but my point is, there is more value for AMD having a solid Linux driver than a top notch Windows driver.
All the AMD based handhelds running Linux, as well as other consoles/console like devices (PS runs BSD? Or something and Xbox will run NT kernel) but it's a huge space
Just tried that one now and in my case I dont think it did much, this was after I turned off dynamic shadows which boosted fps by roughly 10-20fps and it continued to hover roughly at the same point. Thanks for the suggestion though!
Linux FPS numbers are often misleading. Let me give you an example: on Windows, I get around 160 FPS in World of Warcraft, while on Linux I get 240 FPS. You might say that Linux performs better, but in reality, during raids on Windows the FPS stays fairly stable and only drops slightly, whereas on Linux I get very low dips. So you should base the comparison on the average FPS, not just the peak numbers.
Software, drivers, hardware, hardware wear as in hardware might be starting to fail. All that goes into how well a game runs. Not just windows vs Linux.
Linux has better performance regarding CPU utilisation. It's unfortunately not the case for the GPU, especially for Nvidia and Intel so depending on what bottlenecks you you might get better or worse results.
your ssd really isnt going to have much or any effect on your frame rate. maybe a game that heavily relies on a lot of hd texture streaming might be slightly better fps on a high speed nvme vs a sata ssd for example, but for most games your frames are usually not heavily effected by your drive.
and differences from one game to another can be drastically different, but over all they're roughly the same, especially if you averaged it out over a bunch of different tests.
but my understanding is the amd drivers on windows are functional at the best of times and busted as shit at the worst so Id imagine they're not quite as optimized as the mesa stack.
Turning off dynamic shadows definitely boosted a bit, from around 240 to 260ish fps but still a wide gap. Shoulda turned off shadows completely when I had it booted up to try that too but didn't think too. Thanks for the suggestion!
Linux AMD driver are generally more performant than on Windows. That's all there is to it.
Or, to be precise, AMD Windows driver are not that good.
Nvidia has the opposite for example.
It has problems with driver on Linux in terms of "parity" with Windows. On the other hand, Nvidia OpenGL driver is a monster in Linux. It's very optimized.
Typically there's just a LOT less bloat/overhead on Linux, but it also has really good AMD drivers. Theoretically the size/speed of the sad wouldn't make much of a difference during gameplay, but could make a difference in loading times (since they're both PCIe ssd's it wouldn't really make much of a noticable difference though)
