I could play TF2 normally with windows with my current hardware. I ditched Windows 10 because my license was revoked after I changed my motherboard.
Now trying TF2 with Ubuntu 17.10, it appears very slow, nearly unplayable. I'm not into playing. I would just like to know if the configuration is OK.
I could run Web3D examples here without problem. I don't know how to determine if the 3D is software or hardware generated. I get only 17FPS for this example. I had 60fPS on Windows with all examples with the exact same hardware. I have the impression the 3D acceleration is not functioning.
EDIT1: Graphic card is Sapphire Radeon AMD R5 230 2G DDR3, CPU is i5-7400
EDIT2: I have 2 screens.
