I have looked for a solution everywhere but so far havent been able to fix this or being closer to understand what the issue really originates from. I have win 10 and AMD radeon 8990 HD and during races I have no problem with this racesim but in the menus its flashes and flickering so bad that at certain times I cant even look at the screen. Makes it almost diffucult finding servers in MP menu and etc. I decided to make a video on how it looks so here it is. Thankful for any help.
Your graphics card has dual chips do it runs in crossfire. This causes the flickering. You either have to disable crossfire or run the game in windowed mode to get rid of the flashing.
