Fixed Issues
Gaming fixes:
- Wuthering Waves: a crash that could happen when NVIDIA Freestyle filters were used together with DLSS Frame Generation
- Star Citizen: a crash when running on the Vulkan API
- Surviving Mars: a crash during gameplay after updating to the R595 drivers
General fixes:
- Occasional black flashes on QHD monitors running at 360 Hz
- Frame rate dropping to 320 FPS on 360 Hz G-SYNC Pulsar monitors
- Meta Horizon Link streams freezing when connected over USB

Our Test Results on RTX 5070
We tested driver 621.01 against 617.42 and 596.49 on an RTX 5070 with a Ryzen 5 7500F at 1440p, across 10 games. Compared to 617.42, the new driver was slightly faster in 5 games, identical in 3, and 1 FPS slower in 2. Across all 10 games, the average moved from 81.0 to 81.5 FPS, a gain of about 0.6%. Against 596.49, it was about 1% behind overall (82.6 vs 81.5 FPS).
Most differences were only 1 to 4 FPS, which is within normal run-to-run variation. In short, 621.01 is a small step up from 617.42 but not a performance driver. Update for the game support and bug fixes above, not for extra FPS.
In our 10-game test on an RTX 5070 at 1440p, 621.01 was about 0.6% faster than 617.42 and about 1% slower than 596.49, so the performance difference is negligible. Full results are in our driver comparison article.
How to Download
You can download the driver from NVIDIA’s official driver page or through the NVIDIA App. If your games are running fine, you can wait, but if you play one of the games listed above or were affected by a fixed issue, updating makes sense.
