I had insane fps drops and stutters with vulkan, staying with dx11...

Tip: don't just look at total fps. In Dota 2 especially, frame timing (how much the little line graph spikes) is really important as it can create that mini-stutter that makes you land an ability just off enough to die. Flatter graph = better (less stutter).

i have a Vega 56 and with vulkan i have some stutters, DX11 seems to be to most stable even though it has less fps

Vulkan is underrated API. Vulkan is best!

[jejeroy]

Vulkan is like the new opengl its REALLLY optimised unlike directx 12 but even the gameplay is better with vulkan you can feel it !

[Emiydus]

A while ago pimpmuckl was recommending people stick to DX11, looking at the video it looks like although Vulkan has consistently higher average, it has more lagspikes / dropped frames compared to DX11. I think most people would notice the dropped frames more but that's just my opinion

edit: still good to know where things stand today. props to TechEpiphany for testing !

the only channel make bunch of video for apu.. like this one comparing apu peformance in dx9 vs dx11.. thanks a lot!

VULKAN or DX9 FOR AMD
DX11 or DX9 FOR NVIDIA

[skatatzisskatenios]

nice test, thanks.
So, , ,
Vulkan for AMD
DX11 for Nvidia

1:13 - Vulkan fps drop x2, lol. if you have 40fps in battle, you can take 20fps freezes and fail match...

[dassatisfan]

AMD and OpenGL is not best friends though

[mtyp_admiral]

Well, I got better FPS on dx11 than vulkan, I dont know why, I updated my driver and used beta & whql driver, and yeah dx11 still better for my RX 560

[BettyHopeMusic]

cant really see a difference... is there actually any visual difference or just fps wise?

[mnsog]

Hey why vulkan API not working on me? it always crashes help i have amd r9 280x xfx

[newchannel-lvuu]

On one pc i have linux installed and play dota wit vulkan and ogl and all warks fine. On another pc i have windows installed i play dota 2 with dx9 and dx11 and its fine. When i use vulkan renderer dota crash, didnt start, dota2 application is hang. How i can fix that problem to play dota with vulkan renderer?

[ANGEL-oxmy]

VULKAN IS BETTER FOR AMD? ANY SUGGESTION PLEASE THANKS ALOT

[MaxMaxxxie]

why does my vulcan drop my normal fps of 160-180 to 80fps when i first tested today ie 2022 Oct 9th, ofc i was downloading a game at the dsame time but its not suppose to hang a stutter all the time like my systems wasnt enough....its i5 11400 rx 6600xt 16gb ram, i ticked the Vulcan DLC and downloaded the vulcan i think which is about 900 plus a lil MB only !!! i dont understand i thought its suppose to be better than the only other option which is Dx 11

[lautarosuarez]

How u use D3D9E ? I just can use D3D9... what's about E?

Das Spiel unterstützt 2GB du hast einmal angeschlossen 1000 Watt dann für den Vulkan einen 600 watt stecker bei Vulkan ram auf 5015 MB Hinweis wenn das spiel Genug Strom hat geht dir Ram Speicher geht nach unten bei Vulkan geht der Speicher nach oben
