Use fewer things that cause objects to be rendered multiple times (such as reflections, shadows and per-pixel lights).Ĭombine objects together so that each mesh has at least several hundred triangles and uses only one Material for the entire mesh.

Use fewer materials in your objects by putting separate textures into a larger texture atlas.

Combine close objects together, either manually or using Unity’s draw call batching.

To reduce the amount of work the CPU needs to do: The cost of both scenarios on the GPU is very similar, but the work done by the CPU to render a thousand objects (instead of one) is significantly higher. For example, if you have a thousand triangles, it is much easier on the CPU if they are all in one mesh, rather than in one mesh per triangle (adding up to 1000 meshes). To render objects on the screen, the CPU has a lot of processing work to do: working out which lights affect that object, setting up the shader and shader parameters, and sending drawing commands to the graphics driver, which then prepares the commands to be sent off to the graphics card.Īll this “per object” CPU usage is resource-intensive, so if you have lots of visible objects, it can add up. Use the Unity Profiler to locate the problem.

If rendering is not a problem on the GPU or the CPU, there may be an issue elsewhere - for example, in your script or physics.

See the section on CPU optimization below for guidance on how to do this. As above, it is generally good practice to keep this number as low as possible without compromising game quality. This could be in skinned meshes, cloth simulation, particles, or other game objects and meshes.

The CPU has too many vertices to process.

A PC manages well even with several million vertices, but it is still good practice to keep this number as low as possible through optimization. Generally speaking, aim for no more than 100,000 vertices on mobile. The number of vertices that is acceptable to ensure good performance depends on the GPU and the complexity of vertex shaders.

The GPU has too many vertices to process.

The more batches are being rendered, the higher the cost to the CPU.

Check “batches” in the Rendering Statistics window.

CPU is often limited by the number of batches that need to be rendered.

If a lower display resolution makes the game run faster, you may be limited by fillrate on the GPU.

Lower the display resolution and run the game.

GPU is often limited by fillrate or memory bandwidth.

CPU are quite different (and can even be opposite - for example, it’s quite common to make the GPU do more work while optimizing for CPU, and vice versa).Ĭommon bottlenecks and ways to check for them: The first rule of any optimization is to find where the performance problem is, because strategies for optimizing for GPU vs. The graphical parts of your game can primarily impact on two systems of the computer: the GPU and the CPU. Below are some simple guidelines for maximizing the speed of your game’s rendering.

even if this problem of slowlyness doesn't occur neither in Gnome-Shell or Windows (but the last one is probably due to the fact that the Nvidia Optimus works and on Linux it doesn't.Good performance is critical to the success of many games. In OpenGL > 'Texture Filter' select 'Fast' instead of 'Good', and choose 'Texture Compression' (this feature will use a little bite more of the process but will help with graphics so it is at your choose (you can have the 2 options unselected though)Īnd I think it is all you can do (for me even Unity-2D is slow so I think it is the fault of my processor.Disable Sync to VBlank (as mentioned by In Composite Plugin > Select your Refresh Rate (available at Screen Settings) and then uncheck 'Detect Refresh Rate'.

Use the proprietary ATI drivers available in Ubuntu.Īfter installing ccsm (Compiz Config Settings Manager) : I am in the same case as you because I use an Asus 1215N with a Dual Core ATOM processor and an Intel Graphic card since the Optimus doesn't work natively.īut you can still do some configurations to help a little bit with the problem like this : Unit圓D makes the system extremely slow but only low Graphic Card and/or can actually reproduce the lag and slow animations. Too much useless animation and effects activated in Unity.
