😱 [GPU effects error] If you press number pad 0 or blood up, you can't see the preview and have the same error as in the picture. I'm posting it because I think there might be some people with the same error as me! If you look at File -> Project Settings -> Video Rendering and Effects, There are 3 choices in Use! You can change it to Mercury software acceleration there. CUDA's available on all Intel-based computers! -Opencl is only available on windows with NVIDIA! You can use either computer:) I used CUDA and it was solved! The adobies made the site so uncomfortable that I managed to find them.ᄃᄃᄇᄇ It's a graphic problem, so if you can't do it, you can find a solution here!
