MSAA in games extreme low performance

[Alberto8]

MSAA in Directx11 games that are not optimized by intel or at least they are not in your list of drivers has a really high performance impact.

For example ALL sim racing games Le Mans Ultimate, rFactor2, ACC, Call of duty WWII or Modern Warfare, etc

Assetto Corsa Competizione is TAA but same problem.

Could you please include Sim Racing games in your pipeline?

Hello Alberto8,

Thank you for posting in the Intel® Communities Support.

We appreciate your feedback regarding MSAA with Intel graphics. However, please be advised that when enabling Multisample Anti-Aliasing (MSAA) is a type of spatial anti-aliasing. It greatly taxes resources such as textures, bandwidth and fillrate. Though it is less performance intensive than Super Sampling Anti-Aliasing, it is possible for MSAA to be multiple times more intensive for a given frame than other techniques like FXAA, SMAA or MLAA. The higher the type of MSAA selected (2x, 4x, 8x, 16x) the higher the impact in performance.

A performance reduction when enabling MSAA in your videogames is expected behavior.

However, before we will look into your concern and see what we can do moving forward, kindly submit to us your system scan using Intel SSU? This way we can have a better understand what Intel graphics are you using to run these games and for our developers to have a better insight as well.

Best regards,

Jay B.

Hello Alberto8, 

I am just following up about the SSU logs so we can further check this for you. Feel free to reply to this post. Thank you.
