Thanks for info. Updated first post

 

Will try 442.88. The previous 442.86 from April 1 have worked flawlessly since installed (fixed the XCOM 2 crash introduced with WHQL 445.75).
Thanks,

Aside from adding new features which current game engines won't be using yet, the changelogs also list fixes and sometimes performance improvements in general -- has anyone tested whether the beta drivers, based on Vulkan 1.2, offer any improvements for current games compared to official driver releases (such as 445.87) based on Vulkan 1.1?

 

yes, they give better performance. also on older pascal cards

 

How much? 1%, 10%, a zillion %?

Is it a function of higher minimums, avg, max fps? Or more stable frametimes?

Details!

 

There are more Videos under "Vulkan 1.1 vs 1.2"

 

Huh wouldn't have expected any differences as the game itself should be 1.1. whatever SDK it was built against but I suppose the driver side still factors in whether it's VLK bug fixes or various optimizations either towards Vulkan or it's extensions or game specific.

Wonder if the ray trace update will bring in the extensions or the full 1.2.135.0 SDK and 1.2 VLK baseline. Pretty sure the earlier titles mostly just brought over extensions that were then standardized in 1.1 for updates like CAS in Wolfenstein New Colossus.

That one outfit from Twitch is going to look real fancy once that's implemented at least.


Glitter and flutter!
Or...not.
