Hi liigma9966, not sure what you mean by grainy. The main menu has an effect that make it look distorted. But it will go away once you load the game. If you're experiencing visual artifacts while in game you could try switching the rendering engine to OpenGL to do so create a shortcut to the game exe and add the following flag:
--rendering-driver opengl3
in the target field just after the .exe and outside the quotes if any.
It could be so. In our testing be managed to get the game barely working on a computer with integrated graphics from around 2020. However, in its stock configuration a ThinkCentre Centre E73 can allocate a max of 2GB of video RAM (that is taken from the system RAM). As the game needs 1.5GB to fit in the textures, only 512MB remain for the rest of the system. This may cause a severe drop on performance as the OS will swap in and out the texture buffer constantly to save on RAM for critical tasks. And may lead to the issue you describe.
Hi ligma9966. You can try running in windowed mode and pick a small resolution. That would reduce the workload on your GPU. Also disable V-sync and set FPS cap to around 30. If that's not enough and you really want to push it then set scale mode to view port and lower the 3D scale up to 0.6 (be aware that doing so will drastically decrease the image quality). You can still pull it lower but below 0.5 you get potato quality. Hope it helps.
