DXVK is a game changer in FNV

[Mak10z]

If you have a newer Videocard that supports Vulkan, I highly recommend installing the DXVK wrapper in to FNV. I went from 40-50fps in a heavy modded TTW + ENB install to a fully stable locked 60fps in all locations (that I have tested so far)


download the archive from here https://github.com/doitsujin/dxvk/releases
pull out the d3d9.dll and DXGI.dll and drop it in the root directory of Fallout New Vegas.
and go from there.

if you use enb, rename the new DLL to DXVK_d3d9.dll and edit your proxy settings as such

[PROXY]

EnableProxyLibrary=true
InitProxyFunctions=true
ProxyLibrary=dxvk_d3d9.dll

Edit: adding, found a fork of DXVK that uses async shader compiling, so its even better than before! :) https://github.com/Sporif/dxvk-async

How do I exactly get the DLL files from that GitHub link?

[Mak10z]

click on the dxvk-1.7.2.tar.gz link, and open it with winrar or if your using linux just untar the file.

Ah I see, Thanks . I'm seeing around 9-10 FPS in a certain known problematic spot in the strip!

Oh my God! Thank you for explaining how to do it as well. I've used Vulkan with GTA IV already to get more frames but I had no idea you could do this to FNV! This is my favorite game everrr and now I'm getting stable FPS!

i made this

EnableProxyLibrary=true
InitProxyFunctions=false
ProxyLibrary=dxvk_d3d9.dll

but disable enb functions ... wich of the dll on the rar ? wich enb version you try

[JoMo]

Any chance that this helps with crashes?

it may, but I doubt it. its still a command wrapper, so any base game bugs will still be there.

how do i make it work? im trying everything and aything and it wont work with enb pls help!

[Mak10z]

make sure you're using the 32bit (x32) version of the DXVK D3D9.dll and dxgi.dll
the x64 version wont hook correctly

I use Reshade unfortunately which installs its own d3d9.dll. Is there a work around for this?

The Vulkan version of ReShade doesn't require the d3d9.dll. When you use the ReShade installer, there is an option to enable it for all Vulkan games. Once you do that, it will be enabled in FONV running under dxvk.

Alternately, you can use nVidia Freestyle to apply reshades instead.

Depth-reliant ReShade effects still won't always work properly with MSAA enabled.

You also cannot use dxvk with New Vegas Reloaded - you will experience some major graphical glitches.

Edit: To those doubting that dxvk can help - my system specs are in my profile. I'm not running a potato. While I don't need the extra FPS that dxvk can provide, the frame pacing is vastly more consistent than under DX9 in New Vegas, probably down to driver optimization - you have to remember, nVidia hasn't tuned or optimized their DX9 drivers in many years at this point. They are essentially a legacy feature - the same reason that MS has it's own d3d9->dx12 wrapper solution for re-releases of old games.

While I don't use dxvk due to the mentioned conflicts with NVR, it does offer a very smooth experience just in terms of frametimes, not to mention overall framerate.

I tried both versions and they both made my game lose an average of 20fps and made loading times 5 times longer.
I don't think I used the wrong files. I got the x32 dlls, renamed the d3d9 one and made the ENB load it. In both tries the main menu had 30fps max, walking around in zones where I had 40fps turned them to 20-25 with the new files and interiors seemed capped at 40.
WIthout DXVK my game runs perfectly unless there's 40 npcs all in one place.

Thanks, I give that a try.

DXVK can induce additional stutter as shaders must be converted (while no precache system is available). In theory, after a while these stutters should disappear, though no one has observed this yet.

Which is ironic as the mod's goal is to eliminate stutter.

"Modern" CPU's can bruteforce this, though to exactly what extent will vary. Users that fit into the category won't need DXVK in the first place as they can maintain 60 fps with mild dips into 55.

The biggest problem isn't with frame rates, it's stability. Which DXVK doesn't do anything to help with. Many mods, tweaks, and guides exist on the topic. Yet none are perfect. And you will see a crash no matter what eventually.

As I said, it's not always about pure FPS. NVs frame times can plot all over the place, even at "60" FPS under d3d9. Under Vulkan, they tend to be extremely consistent, resulting in a perceptible benefit to how the game feels.

bro my game crashes at startup after using this
