the timing of the RAM might be higher than your previous setup, which will lower the cpu's ability a bit
the xmp profile might have set the rams clock speed to a number that decouples ryzen's fabric clock out of sync with eachother if you have an amd cpu, which will significantly hamper the cpu's ability
16gb of ram for vrc is perfectly fine, cpu single core speed is the main bottleneck since the game is optimized like shit and just pegs a single core for most of its operations, especially dynamic bones
vram is also an issue but you can easily manage that by lowering the game's vr resolution, using the clear vram mod after a while, or not showing absolutely everybody's avatars
