Same thing happens for Smite on Fedora 28. I tried to use the Proton beta as well and it still doesn't work!

tried again with 3.7-6 - this time the .net installation doesnt seem to be needed, but the game fails to launch silently. Going through the log, these seem to be the relevant lines:

158765.627:0037:0038:fixme:mscoree:ConfigFileHandler_startElement Unknown element L"generatePublisherEvidence" in state 4

Same thing happens with Viscera Cleanup Detail: Shadow Warrior (255520)

I've tested it before and is not that the .net installations isn't needed @Cuddlypuff Seems to be that on the 2nd run it assumes that it's already installed.

2nd run launch: steam-255520.log

I have the same problem.

I have the same problem with Viscera Cleanup Detail: Santa's Rampage (265210)

By the way, shouldn't this installation (.NET framework) be silent?

I've managed to get this game working with Steam Play, here's how to do it......

1. Install the game.

2. find & remove the redist folder & anything that has dotnet in it's name, run the game & wait for it to crash, should take a second or so, if you forget this delete the pfx folder & start again from here.

3. Use Protontricks to install dotnet452 (takes about 5 minutes). at the end click restart now button. "protontricks 246900 dotnet452"

4. download the 64bit vcruntime2012.exe from here https://www.microsoft.com/en-us/download/details.aspx?id=30679

5. use protontricks run taskmngr & use that to run the exe you downloaded. it may seem like nothing happens, just wait a few seconds then shut taskmngr & winetricks.

6. run the game but choose 64bit & only 64bit.

7. enjoy the game.
   ps. This also works for both the extras, Santa's Rampage & Shadow Warrior.

The technique I used above no longer works with the latest Proton 3.16 Beta dotnet40+ refuses to install at all even after multiple attempts.

same issue in 3.16-4, tried normal launch and 64-bit launch - doesnt have any issue installing anymore but fails to start

steam-246900.log

Should I change the issue title to better reflect current state?

Same error as of 3.16-6 Beta!

it's working, but you need to click on Steam menu and check for updates.

It now installs now in proton 4.2-3 and reaches the games splash screen, but crashes when launching.

With Proton 4.2-4 the game now works out of the box. The first installation of dependencies complains once about a missing file, but doesn't have any negative impact. There are some stutters here and there but generally it works pretty nice.

Was also able to improve the performance a lot by using D9VK 0.11.

https://gist.github.com/NoXPhasma/d3ee077b33da13dcf7761c76c40e2a79

Can confirm its working out the box now. Performance isn't great though.

As I'm the original reporter I figured I should chime in - tried again with 4.2-4 and it worked 100% for me, no performance issues at all anywhere. I'm running a GTX 1070 with 430.14.

Since others are still having issues I'll leave my issue open.

I don't have the base game of VCD (yet), but I do have the stand alone Shadow Warrior version and it also installs and works great now. Best 2 hours I've spent in a long time. But bad performance seems to be directly linked to how many props are cluttering the map. The more that were removed, the smoother the frame rate got. Reducing shadow and other graphical effects improved performance. But still, with my hardware, shadows shouldn't be a problem. Some improvements can definitely be made here.

I now have VCD and I've spent a lot of time on it. I can say for sure now where a lot of performance issues are coming from. They appear to be related to the "decals", such as blood splatters, dirt smudges, burn marks, bullet holes, bloody foot prints, and so forth. For some reason they are causing the biggest performance issues. By turning off bloody foot prints in the rules menu just before starting a new level, I'm able to keep the number of decals from increasing too much and this helps keep the framerate above 30.

How to easily reproduce this yourself:
Load a level and find a corner with some body parts. Walk to the other side of the map, look in the direction of that corner, and make a note of the FPS. It's at a comfortable 60.

Then go back and start making a mess. All I had to do was walk in circles for about 2 minutes and push the body parts in random directions with the broom. This tiny 2 minute mess dropped the frame rate from 60 down to 30.

Then go back to the other side of the map, look at the corner, and make a note of the current FPS. You'll notice the frame rate stays the same; 30 FPS. So the "decals" will always be a problem whenever you look in their direction, regardless if you can see them or how far away they are.

Then go back and clean up all of the blood. Do not throw away or destroy any of the props. Only remove the blood splatters. You'll notice the frame rate has returned to normal.

Finally, go back to the opposite side of the map one more time and look at the FPS. Again, the frame rate is at 60.

I've done this test multiple times with different graphical settings and nothing impacts the frame rate like the decals. At the highest graphical settings, the difference in the frame rate is negligible. At the lowest settings, the decals will still dramatically affect performance and decrease your frame rate.

I never would have guessed decals could affect performance like this, but there it is. I'm hopeful someone with a better understanding of decals and the Unreal engine can find a better solution here. Removing blood splatters from this game undermines the whole experience, and the fact this is happening could possibly hint at a larger problem with Proton and the Unreal engine. Maybe this issue is specific to VCD, or maybe many other games are suffering from performance issues simply because of the decals. I think exploring this issue in other Unreal engine games could possibly help improve Proton. I would do it myself but I can't think of any off the top of my head where I can easily add and remove them.

The game itself works fine, but the editor (Unreal Development Kit version 10907) crashs on launch.

Proton 5.13-5, Kubuntu 20.04

Any way to fix this?
