Optimizing Game Performance: 7 Key Techniques

In this blog post, we will discuss 7 key techniques for optimizing game performance, focusing on efficient rendering, data management, and culling.

Chunking #

Chunking involves grouping objects into chunks for efficient rendering. By grouping objects that share the same mesh, we can render all of them at the same time, significantly improving performance.

Reducing Triangles #

Minimizing the number of triangles is crucial for faster rendering. By eliminating unnecessary triangles, we can reduce the overall triangle count, leading to improved performance.

Data Compression #

Compressing vertex data can significantly reduce memory usage. By compressing position and normal vectors, we can fit more data into a smaller space without losing quality.

Instancing #

Instancing allows us to render multiple objects with one draw call. By creating a base model for the object and storing a list of 32-bit voxel data, we can reduce memory usage and increase rendering performance.

Buffer Management #

Managing buffers efficiently is essential for optimal performance. By creating one huge buffer and giving each chunk a small portion of it, we can reduce the number of draw calls and improve rendering performance.

Culling #

Culling involves ignoring triangles that are on the other side of a model. By rendering only the anticlockwise triangles, we can reduce the number of vertices that the vertex shader needs to process, improving performance.

Face Combination #

Combining faces in two directions can further reduce the triangle count. By storing the second combined face length, we can combine faces in both directions, leading to a significant reduction in triangle count and improved performance.

These 7 key techniques can significantly improve game performance, making the gaming experience more enjoyable for players. By focusing on efficient rendering, data management, and culling, we can create games that run smoothly and look great.
