This will be over 1024 vertices in no time, I am currently drawing vertices with a size of ~500MiB depending on the terrain. The CPU doesn't need to know of all vertices at once, so collect them and upload them to the GPU if they go over a certain limit and begin to fill your buffer from the start again. I use a malloc allocated buffer, its size is never decreased, I initially allocate an educated guess + some extra to be safe, then if it really happens to run ot of memory I simple resize it depending on how much is left with another educated guess + some extra.
