I wonder if hidden line removal is to much for the C64.
I also found this.

80 Column for C64

This intrigues me. I used an ML program from God-knows-where (I wanna say Transactor, since that's where I found CBAT) in my BBS program which allowed the 64 mode of the 128 to use the 80-column VDC. It's not very big and I may still have the source code -- I never got around to folding it into the final package though I had a test package compiled and running.
I also had a working driver for the Batteries Included BI-80 expansion card. Neat stuff.

I wish I had 80 column mode back then for the c64.
The Chameleon seems to be a good add-on. I would have to see if it has 80 column.

Does the C128 have the ability to turn off the display like the Plus4 has?

When I looked at the source code in the link, these are routines to use a graphics screen to emulate 80 column mode (or implement an 80-column bit-mapped screen, however you want to look at it.) I know Novaterm did this, and it worked very well, though you needed a monitor or a good TV to view it clearly. Fortunately I had really good eyes.

I don't know how the Plus-4 does it. I know I've seen the 80 column screen blanked, but I have no clue if that was hardware blanking or a trick like changing colors to all black. So much old code to go over!

They say if you turn the display off you can get ~20-30 percent increase in speed.
