Bonjour, je joue sur un pc portable et la fluidité est horrible! Ma résolution est de 1920*1080 mais je dois mettre la résolution la plus basse possible (1240 x je sais plus combien ) pour pouvoir à peu près jouer, et meme comme ça c'est pas fluide du tout... Quelqu'un a une solution? Merci

Finalement j'ai trouvé la solution.
Pour ceux qui ont mon problème, suivez les instructions de ce post trouvé sur le forum steam du jeu:

There are multiple ways to get to Nvidia control panel; you can try looking around the task bar, searching the start menu, looking around programs & features, or maybe by right clicking on your desktop. Once it's open, click on 'manage 3d settings'. Click on the 'Program Settings" tab; this should bring up where you add profiles that determine what graphics processor certain programs use. It may need to load for a bit. Click the "Add" button & you'll be able to see recently opened programs you can add OR browse your computer for programs. If you don't see Apotheon(Or whatever other program you want to add) you can click "Browse" and look in your computer for programs to add.
For Steam games, the usual file path is C:>Program Files(x86)>Steam>steamapps>common
From there you can choose whatever game folder & find the .exe that IS the game; the file type column should say 'Application' and the little picture should be the game's logo. Choose the application & add it.
Once a program has been added to that list you can select it to see what processor it uses & tell it to use what you want. In pretty much every game's case you want it to use "High Performance Nvidia Processor"

Merci
