I already have try everything possible to solve the problem.
Update all drivers, windows, DirectX, Frameworks.
I reinstalled the Nvidia driver.
I verify the windows data.
I verify the Warframe data, optimize the Warframe data, completely reinstalled Warframe.
I searched online for solutions, but everything I found I have already tried, the only thing I don't try is deactivate ASLR cause this is for the safety of the PC.
I have changed the settings to low, I changed the DirecX Version to 11 in the launcher.
I wouldn't write in this Forum if I don't have done anything possible to solve the problem.
I play Warframe since 2015 und got nearly 8500 hours and I never got a similar problem.
I don't know what else I can do, I can restart the PC than play ~1 hour and than restart again and so on, thats not fun. If a clan member ask for playing I reject it since the last update cause it starts to stutter very soon and this is more than just annoying.
And I have no problems with any other game.
