Since we can now downscale the game view in 5.4, I'd like to set my game view in the editor to a 5K resolution (5120x2880) for various reasons, like creating image sequences for film. When I do that by creating a fixed resolution preset for the game view I get following error message: Code (CSharp): GameView size clamped to maximum texture size for this system (4096) UnityEditor.HostView:OnGUI() Resolutions until 4096 work fine. Could this be a hardware problem of my computer? My ATI Radeon 6750M theoretically should support up to 16384x16384 textures. I'm on OSX 10.11.5 with 5.4b22. To see if it's a general problem with textures of this size, I also tried just importing a 5120x2880 texture with max texture size to 8192. But an imported image with white background and 1px black lines are rendered gray and downsampled in unity. At the same time, Texture2D.width of the (not packed) sprite texture says it's 5120 wide. Here you see the difference between the picture in photoshop (only black and white) and the same texture in unity (point filtering, without mipmaps, max size 8192). Any ideas what could cause this?
