Depending on the game, Intel will switch between their native driver for DX9 and using DXVK to run DX9 stuff via modern Vulcan instead. The driver will decide.
Intel doesn't ship "native" DX9 drivers for Arc. It's either Microsofts D3D9On12 or DXVK.
According to Intel they now do. It will be either their new native DX9 driver or DXVK depending upon the app.
They do since 3950 and newer builds. That's why 3953 provides almost double the fps in games where they use the native ones (such as CS:Go), not to mention a lot better frametimes.
Mostly eSports titles have those native ones.
There is no native DX9 driver. Just D3D9on12. DXVK is basically "on vulkan" isntead.
The computer knows better ;).
Computer says no.
The computer isn't making the decision, the Intel driver just includes a handmade list of known titles telling it which library to use for each.
