PS3 Emulator RPCS3 Developers Work Around Nvidia Driver Bug, Boosting Performance Up to 37%
Key points
- RPCS3 developers found a workaround for an Nvidia driver bug.
- Performance increased by up to 37% in games like Gran Turismo 5.
- VRAM usage dropped from 7.1GB to 4.8GB in Gran Turismo 5.
- RPCS3 developers are attempting to contact Nvidia about the bug.
Nvidia Driver Bug Workaround Discovered
The development team behind the open-source PlayStation 3 emulator, RPCS3, has identified and implemented a workaround for a specific bug within Nvidia's graphics drivers. This discovery has led to significant performance gains for users running the emulator on systems equipped with Nvidia GPUs.
Performance Improvements Detailed
Testing conducted by the RPCS3 developers shows that the workaround can improve gaming performance by as much as 37%. For example, Gran Turismo 5 saw a 37% increase in frame rates and a reduction in VRAM usage from 7.1GB to 4.8GB. Other titles, such as Saints Row IV on a GTX 1060, experienced a 20% performance boost. The developers noted that "most games are impacted" by the bottleneck.
AMD GPU drivers are not affected by this bug, and therefore, systems with AMD GPUs do not see any change from this workaround.
Communication with Nvidia
The RPCS3 team has attempted to report the driver bug to Nvidia through developer forums without success in the past. Following public announcements of their workaround, Nvidia Software QA boss Manuel Guzman has directly responded, indicating a potential opening for communication regarding the issue.
