After fixing a critical bug with the 430.53 hotfix update about a week ago, today Nvidia released the GeForce Game Ready WHQL 430.64 drivers, bringing security updates, a few fixes, and Game Ready status for RAGE 2, Total War: Three Kingdoms, and World War Z.
RAGE 2 and Total War: Three Kingdoms will be releasing over the next two weeks on May 14 and 23, respectively. World War Z saw its release about a month ago on April 16, so it’s been a while; but with this driver, per Nvidia, gamers can expect a performance boost of up to 18% with Vulkan:
As mentioned, this driver also brings with it a few security updates, which the company details in its Security Bulletin 4797. In particular, the update addresses CVE‑2019‑5675, CVE‑2019‑5676, and CVE‑2019‑5677.
Here’s everything that was fixed with this release:
- Fixes higher CPU usage by NVDisplay.Container.exe introduced in 430.39 driver. 
- [3DMark Time Spy]: Flickering observed when benchmark is launched. 
- [BeamNG]: The application crashes when the game is launched. 
- [Shadow of the Tomb Raider]: The game freezes when launched in SLI mode. 
- [Hitman 2 DirectX 12]: The game crashes. 
- The desktop flickers when videos are played on the secondary monitor. [2552316, 2565509]
There are a few known issues as well:
Windows 10 Issues
- [NVIDIA Control Panel]: When the 3D Settings page->Vertical Sync setting is set to Adaptive Sync (half refresh rate), V-Sync works only at the native refresh rate after rebooting the system. 
- [Sniper Elite 4]: Game may crash when using R400+ drivers. 
- 200515120 - Forza Horizon 4: Game may crash when driving through specific tunnel
- 2583604 - Grand Theft Auto V: Brief flicker/corruption when MSAA is used
- 2587043 - Tom Clancy's The Division II: Game may crash when playing in DX12 mode
Along with all of this, there are new or updated SLI profiles for these titles:
- Imperator: Rome
- Insurgency Sandstorm
It’s worth remembering that the last WHQL-certified release – 430.39 – brought support for the Windows 10 May 2019 Update. Unfortunately, it also brought with it a bug that caused sporadic high CPU usage, which was fixed with the 430.53 hotfix. This release, hence, is the first WHQL-certified release with that fix, and support for the May 2019 Update.
