Other than cost, is there a reason high end computer gaming rigs don’t use industrial graphics cards (think NVIDIA Quadro, e.g.) for better performance?

Question

I’ve been looking to build out a gaming PC and came across these types of graphics cards. Obviously, I’m not spending 10k on a graphics card, but I remember using systems with these types of graphics cards when I did treatment planning for cancer radiation therapy because of the amount of ray tracing over thousands of simulations, and I got to wondering why those with deeper pockets than I have dont just go for broke.

They would do nothing. Professional graphics cards have 3 things consumer cards do not.
1. More RAM. This will do nothing for you. Even at 4k you are not using the 11Gb on a 2080ti so 16 or 32 will do nothing.
2. ECM RAM. This is needed for complex simulations to detect and correct errors. It would do nothing for graphics.
3. Double precision. This allows you to calculate results out to 64 rather than 32 bytes. I can’t think of anything you could use. Double precision for in gaming. Maybe running the game at like 128k resolution. Displaying the seen at 2000% of the Adobe RGB spectrum?
Double precision is used for super accurate simulations where you need to know the location of say a water molecule to like 30 decimal places.
