My steps so far
Installed The Sims 4 (origin).
After Lutris installed, logged into Origin and installed the game in there.
Game starts and seems to act normally but lags.
Tried to turn on DXVK and esync but DXVK doesn’t stay switched on as soon as i save and leave the settings.
System set up
Running an old Dell Latitude Laptop.
Graphics: Nvidia NVS 5200M
CPU: Intel 3th gen i5
OS: Xubuntu 18.04 LTS
Wine Ver: 4.6 Staging
Driver: Nvidia 418
The game ran fine on the same device with Windows 10
Perfomance in Sims 4 is a known issue. However, this might significantly improve in the future with D9VK. It currently has some rendering issues in Sims 4, but I am helping Joshua Ashton (the dev) with whatever I can to get those resolved as soon as possible.
Thanks a lot, @cxf for the great answers and also thanks to @citrusalex for working on it, i hope you come to a solution and i would like to hear from it when it is so far.
I would have loved to help out in this case but sadly i’m pretty much of a newbie with programming, linux and all of that, but i am ready to learn, so when there is a way i could help in any way, let me know! (i’m unemployed cause of mental reasons, so i’ve got a lot of time)
Thank you guys for the fast replies and that you stick around with me, that was a great experience!
