Developers, please take a look at DXVK to improve performance

don't ask me but it can happen on some circuits, while on others i already got 60 to 75 fps, now performances dramatically improved

but still, keep in mind i'm actually using linux, so things may differ...

 

Thank you! I removed that post, so not to bother with something that would answer itself after release.

 

Regarding manual usage of later versions of DXVK, the last I'm able to run on a 6700XT (on current 24.10.1 drivers) is 2.4.1.
Both 2.5 (2.5 should be bugged, no AF in dx9) and current 2.5.1 fail on launch/splash screen, unable to create device. Haven't found a workaround yet.


A small update: The situation didn't improve with the latest 2.5.2 on current 24.12.1 drivers, now it'll spew another error:
(so I'm back to 2.4.1)

 

is dvxk planned to be upgraded ? There are just some small artefacts on some wall textures, like at Interlagos.
With dx9 I have constant stutter micro-freezes, with dvxk it's 100% smooth.

 

I desagree. By miles one of the best simracing by miles

 

Another update to the above, the newest 2.5.3 dxvk d3d9.dll runs fine again on my system + 24.12.1 on a 6700XT, unlike the previous 2.5.x versions that would prevent R3E to start.

(Since 2.5.x exclusive FS has been forcefully disabled, so you might with to check the notes on how to enable it back with a single line on your dxvk.conf file: "dxvk.allowFse = True", if you require it for VRR to work)

 

Why is there an openvr_api.dll in the Vulkan directory?

 

2.6 seems to work fine. Need to do some more testing tho.

 

Very late reply, but only recently noticed a regression since 2.6.2.

On my system (6700XT/24.12.1) any version released after (but not including) 2.6.1 will lack AA on AT textures such as trees, fences, 2d far horizon, etc. Also, they won't dither anymore (fences now turning invisible past a few mip-maps) -- so it'll look the same as vanilla DX9 without external MSAA enhancements. Tried most recent 2.6.2 and 2.7, both behave that way.

PS: Using d3d9.forceSampleRateShading = True (closer to SGSSAA, way more taxing on GPU) as a workaround will return antialiased transparent edges, but not previous dithering (which allowed longer distance fence render). I guess the culprit was this change introduced in 2.6.2:
"D3D9 vendor hack features are now only exposed when reporting a GPU vendor that supports the given feature on Windows. This may avoid issues in case games make assumptions based on vendor IDs rather than format queries."
So, using d3d9.hideAmdGpu = True to report an NV, returns that dithering (maybe botched A2C?), but creates issues like missing car shadows.

Update: 2.7.1 has a note about fixed MSAA resolves in some D3D9 games, but doesn't change the above. Further on, the dev doesn't intend to revert or allow previous behavior seen up until 2.6.1, were available D3D9 hack features weren't checked against GPU vendor.

 

Probably a dumb question but can VR somehow work with this ?

 

Since Raceroom VR uses a DX10 layer, have anyone tried using a DX10 dll of DXVK instead of DX9 that is used for the monitor version of the game?

 

I'm really late to this party but has anything changed regarding VR and DXVK? I would really like to have this performance boost in VR. Is there a way to add DXVK as a start command in the start options, so R3E also starts in VR with DXVK?

 

Does that now work in VR ? I Tried months ago and it just crashed. Be awesome if it did though.

 

I dont' know... using 32:9 HDR monitor at 5120x1440, with RTX 4090 and the game is butter smooth on max settings, with 150-240 fps depending on the track. Loving the new rendering improvements!!

 

No, this doesn't work for VR. Hence my question here: https://forum.kw-studios.com/index....-improve-performance.18014/page-4#post-256078

 

I meant this option. Currently, it looks like you can only do one or the other, but not both.

 

DXVK will be used if you have DXVK .dll files in the same folder as the game executables. For 64 bit version that would be Steam\steamapps\common\raceroom racing experience\Game\x64

You can download DXVK files from here: https://github.com/doitsujin/dxvk/releases

Maybe if you put dlls of both DX9 and DX10 in there it can work?

But: https://forum.kw-studios.com/index....-improve-performance.18014/page-4#post-256426

 

Were the dxvk files updated by kw-studios with the latest update or are they still the same version as dxvk was introduced to Raceroom?
