Describe the issue

Game works fine without DXVK enabled, but the performance is quite poor. When DXVK is enabled it crashes after champion select with Could not initialize Graphics Device popup. vkcube works just fine...

Screenshots

Please let me know if I should provide any more outputs. I don't see anything suspicous running leagueoflegends start in verbose mode. Thanks in advance!

Please read this https://github.com/doitsujin/dxvk/wiki/Driver-support

Note: Nvidia's Kepler architecture (most GTX 600 / 700 series) is no longer supported. Please use DXVK 1.10.3 in combination with these cards.

Maybe this is your problem

@rurigk: Thanks for the information!

@oopjot: If the issue is indeed as described, you may try out DXVK 1.10.3 by changing this line in the script to DXVK_VERSION=1.10.3. https://github.com/kyechou/leagueoflegends/blob/bd681ad02a9d25ea9840c3ba9e2621aba8202cc4/leagueoflegends#L345 And then run:

leagueoflegends rm-dxvk-cache
leagueoflegends del-dxvk
leagueoflegends add-dxvk

Or alternatively just reinstall the whole thing:

leagueoflegends reinstall
