Re: 3d View suddenly impossibly slow I had similar issues on my Laptop with an on-board Intel HD graphics card as well as an on-board Nvidia GeForce. 3D view in SH3D was terribly slow, it took abot 20 secs to render a single image. At the same time, I noticed in my NVIDIA monitor application that the graphics card was not used at all. So all 3D calculations had to be done by the not-so-fast Intel HD card! I opened the NVIDIA system settings, there "3D settings" and there was an option "preferred grahics processor" which was set to "automatic. I changed this to "NVIDIA high performance graphics processor". There was also an option "OpenGL rendereing processor" which was also set to "automatic". I also changed this to "GeForce". After that, the 3D view in SH3D was lightning fast. I also noticed in the NVIDIA monitor application that there was now a java process using the graphics card. This means that the "automatic" settings that were set before didn't automatically choose the fast GeForce but the slow Intel HD card to do the rendering! So always make sure your graphics card is actually used for rendering the 3d view in SH3d and change your grapphics card settings accordingly! |
