Building 2D Games Quickly Using ClanLib SDK

• Build a large dynamic vertex buffer sized for N sprites.
• Each frame, fill the buffer with transformed quad vertices for visible sprites.
• Bind atlas texture once, set shader, and issue a single draw with index count = N * 6.

This reduces thousands of small draw calls to one or a few large ones, drastically cutting CPU overhead.

11. Final notes

Performance optimization in ClanLib projects is an iterative cycle: measure, change, and re-measure. Focus on reducing draw calls, avoiding GPU stalls, managing resources efficiently, and using multithreading wisely. Small, targeted changes informed by profiling typically yield the best returns.
