HI Brandon,
The Pixelation in the Lava has mostly to do with your Material and with your Render Resolution and with the amount of Denoising and the amount of Samples.
I have no idea, what Turbo Tools does with your Settings.
It might also have to do with the Resolution of the Fluid Sim and the smoothing.
And no, 20 Nodes is certainly not too much for Blender!
A simple calculation shows that 30 seconds of animation with 24 Frames per Second and 2 minutes Render time per Frame, already takes 24 hours to Render.
