How can I test my multiplayer game on same PC for STEAM

Development Programming & Scripting Multiplayer & Networking

I want to test my game on the same PC, but 2 steams do not open on the same PC (Sandboxie is not fully compatible.)
I used VirtualBox, but this time I get the error “D3d11 compatible gpu feature level 11.0 shader model 5.0” when opening the game.
(Directx etc. installed.)

Do you have a suggestion?

I remote into my work PC that is at the studio I work for, so I guess renting a remote PC could work. Otherwise, you’ll have to depend on a friend to help with testing.

If you’re not explicitly using steam functionality, then you can run a second copy of your game (if you have the CPU/GPU power to handle it) with -nosteam on the command line and try it that way.

VirtualBox can probably be configured to work, but you’ll need to research how to get that to happen. Oh, if you’re using Win 10 and have the horsepower, also, you could probably install WSL2 and run the Linux version of Steam and build your game for Linux as well and run that. (might work with WSL1 too, not sure)

If you’re developing something multiplayer, it would definitely be a benefit to buy a second computer that can handle it.
