This is because Bottles found only 1 GPU (Intel). How many gpu do you have?

I have a laptop with intel graphics and an amd gpu.

Does it works setting the DRI_PRIME=1 env var and disabling the discrete gpu option?

No, it does not.

I think this is not a optimus laptop

It isn't, but DRI_PRIME=1 works without any problem on my laptop with steam, lutris and basically every application on my system.

[mirkobrombin]

I've taken a look at how we manage gpus in bottles and DRI_PRIME is overwritten according to your gpu, so as the amd one is not listed, it forces intel. Did you set DRI_PRIME from the bottle environment variables section?

[Tungsten842]

Yes
