"The memory management driver feature is automatically enabled by the sim if you are in the new driver, in SU10. There is no additional action or patch required by the sim team.
Again, just to be 100% clear on this:
- If you are not on the new driver, the sim will not attempt to engage the DX12 driver memory management feature
- If you are on the new driver, DX12 driver memory management will be enabled by the sim"
