My question is simple. If anyone knows the answer I'd appreciate input. I'm running Raspian OS (Debian64bit) via VirtualBox and it seems to be running my webgl code fine. But I'd like to know if the performance would be the same on a Raspberry Pi running the same OS. I don't know if the specs matter. let me know if they do and I can post them.
No its not, you're not emulating the hardware of a raspberry pi but just the architecture.
