Vulkan & D11

[Cowboy]

Hello guys,

I haven't started a game yet. I was setting up my graphics options and noticed that my in-game fps was around 20-25 with vulkan, yet with D11 I was able to achieve an almost stable 100 fps.

(I9 9900K, 2080 Ti, 32GB RAM, December GPU drivers. ultra-wide monitor).

Am I in the minority? I only ask because I read that D11 should only be used if the use experiences problems running the game.

Kind regards.

Grant.

Well that is a big difference in frames... Yes getting a few extra frames in Directx 11 is normal at this stage but not that much and definitely not with that hardware. So something is off.
Get the new 2021 drivers maybe that will fix it. If not maybe a clean reinstall. Maybe reinstall VC or try turning off in- game overlay that can sometimes cause problems.

Cheers, Dolby. This is the only game that acts this way. Strange. I mean, as long as the game runs well with one API and other games run fine, maybe I shouldn’t mess around too much.

i mean yeah you can just play it on DX11 if it runs it runs...:)

Vulcan runs better for me. In the blighted village my fps drops as low as 15 on DirectX11, but on Vulcan, it runs mostly at 30fps there.

On my system with a 1080Ti and 6850K at 4.5GHz, I can run in Vulkan mode at 1440p with every option Ultra'd out and acieve consistent 80-90fps.

Something's wonky with your driver installation, I'd bet. Try running Display Driver Uninstaller in Safe Mode before reinstalling the latest ones.

On my system with a 2080TI, 5900X, 5120x1440p, 32GB RAM (3200MHz CL14), every graphic setting as high as it can go, and 460.89 drivers, I'm getting 80FPS with vulcan, and 90FPS with DX11.

I did have strange issues with vulcan where it would stutter, and sometimes the framerate would drop terribly (8FPS or worse) occasionally. Same areas with DX11 were super smooth. Overall DX11 just works better for me. More FPS and definitely more stable. I suppose that might change at some point, but I'd rather them devote time to implementing DX12 features.

Vulkan has always been hit or miss. Some systems have absurd performance bonuses, some have absurd performance tanking, some see no difference.

I personally love Vulkan for it’s dynamic render scaling functions and I hope more games utilize it.

I was averaging 1 crash per hour with vulkan. I haven't creashed yet with dx 11

^ That. The results cannot be generalized.
I do not know what exact spec makes it bad on some rigs (maybe a specific GPU feature).
I have no crashes and good performance (i5 9400F / GTX 1660 TI / Win 10 Pro).

On the Wikipedia page, I found the following GPU and CPU do not support Vulkan:
( whether it be on Windows, Linux or Android )

* (AMD) TeraScale 3 (2010) = Radeon HD 69xx Series, Radeon HD 7xxx–76xx Series
* (AMD) TeraScale 2 (2009) = Radeon HD 5000 Series, Radeon HD 6350, Radeon HD 64xx–68xx Series
* (AMD) TeraScale 1 (2007) = R600, RV630, RV610, RV790, RV770, ...Radeon HD 2000 Series, HD 3000, HD 4000.

* (NVIDIA) Fermi (2010) = GeForce 400 series, GeForce 500 series.
* (NVIDIA) Tesla (2006) = GeForce 8 series, GeForce 9 series, GeForce 100 series, GeForce 200 series, GeForce 300 series.

* (Intel) Sandy Bridge (2011) = Core i3-/i5-/i7-2000, Pentium Gxxx, Celeron Gxxx.
* (Intel) Westmere (2010) = Core i3-/i5-/i7-xxx, Pentium G69xx, Celeron G1101.

* and a few less common hardware : Imagination Technologies - PowerVR Series 5 ; Qualcomm - Adreno 300 series ; ARM - Midgard 2nd.

Ps: well, all this to realize no one uses those to play BG3 anyway :P

Hey, guys. I appreciate your comments. Regarding using DDU, that crossed my mind. But...RDR2, Ghost Recon Breakpoint, and Doon Eternal use Vulcan, and they all run flawlessly.

[Jack]

In my experience Volcan will downscale (adaptive) faster on low and midrange computers if they start to throttle, it will for example make Path Of Exile "playable" on my laptop.

The lastest driver made BG3 crash on my computer though, so playing on DX11 atm.

For me vulkan gives me random micro stutters but higher frames and dx11 viceversa
