Hey everyone, wondering if someone can help me find some learning resources. I just threw out my custom 2d canvas rendering code for a project and switched to pixi. Great decision so far - performance is sky high and I'm really liking Pixi's clean API. However, I'm quite green when it comes to utilizing the GPU. Does anyone have recommendations for good general-purpose primers? Specific questions I'm hoping to learn answers to are: how hard should I strive to make every image dimension a power of 2? Is rendering lots of small images and lots of large images (up to 4096x4096) hurting my performance? Is a BaseTexture what gets copied to the CPU, or a Texture?
