NVIDIA has today released driver version 525.78.01 for Linux which includes support for the new RTX 4070 Ti, along with a few select bug fixes. Not that you would want to buy an RTX 4070 Ti, since it's ridiculous for the price.
Apart from supporting the new GPU here's the fixes listed:
- Fixed a bug that could cause the nvidia-settings control panel to crash when using a newer control panel with an older driver.
- Fixed a regression that prevented the G-SYNC/G-SYNC Compatible Visual Indicator from being displayed when running Vulkan X11 applications.
- Fixed a bug where usage of VK_KHR_present_id could cause applications to crash with Xid 32 errors.
- Fixed excess CPU usage in hybrid graphics configurations where an external display is connected to an NVIDIA discrete GPU and configured as a PRIME Display Offload sink (also known as "Reverse Prime").
It's listed as a stable driver, so you should be fine to upgrade to it. They don't specifically mention the 4070 Ti in the changelog but it's clearly listed in the Supported Products tab on the driver page.
