| But if only 1% of the time is spent on the GPU, then the result is basically going to be the same…10 seconds. | But if only 1% of the time is spent on the GPU, then the result is basically going to be the same…10 seconds. | ||

| - | + | Here are some recommendations | |
| - | If you file appears | + | - Keep the overall number of objects in the scene as low as possible and not excessive |
| - | + | - Organize your file in and assign “objects” to “layers”. | |
| - | Also keep the overall number of objects in the scene as low as possible and not excessive | + | - Check for bad objects and rebuild them. |
| + | - Avoid excessive usage of blocks | ||
| + | - Purge unused content in your file like materials and textured. | ||
| + | - Reset your Render mode settings to default //(Options -> View -> Display modes -> Rendered. Pick button at bottom to reset to Rhino defaults.)// | ||
| + | - Insert the contents of your file into a new file. //(This may leave some problem with the file behind.)// | ||

| If different “shaded” display modes all seemed to produce similar performance results, **except the Rendered display mode** which can be significantly slower than the other modes. | If different “shaded” display modes all seemed to produce similar performance results, **except the Rendered display mode** which can be significantly slower than the other modes. | ||
