We can simply use PMB with 3x of the buffer size (triple buffering) and probably the performance gain should be the best. Here is the updated code: The creation:
WebMapping a buffer creates a sync point between the client and gpu, which can be very costly because the gpu often runs a frame or more behind the client. The best option is to use persistently mapped buffers if they are available, but otherwise glbuffersubdata. Edit: buffer orphaning with glbufferdata is also worth a look.
WebOct 30, 2024 · This is termed buffer "orphaning". There are two ways to do it. The first way is to call glBufferData with a NULL pointer, and the exact same size and usage hints it had before.
