performance Windows :/ CUDA vs METAL


Recommended Posts

Very poor performance on Windows, The pen goes faster than the drawing.

 

I have i7 7820X, 32 GB RAM and Quadro M4000.

 

What's the use of having a good team if I have a bad performance?

 

Sure on MAC has better performance than Windows (Metal Vs CUDA)

What tablet are you using?

Have you tried slowing things down in the pen software?

Well that is just wrong!

I don't think Affinity actually uses CUDA... yet. It uses CPU not GPU for most of its work.

Affinity wouldn't really get much benefit out of CUDA, as explained by Ben on this post. (posted by Stokerg)

And then why if you use METAL?

Photoshop If you use CUDA in some real-time effects. And that's what I notice that affinity lacks.

Lots of people probably have Metal set in their preferences but that doesn't necessarily mean they get better performance over that of the OpenGL users. It would be interesting to see what if any performance improvements users are getting using Metal instead of OpenGL if there is any improvements at all.

This Post might help explain the option for Metal on Apple devices, see James Ritson's post:
