An application has requested more GPU memory .... That application will now be closed

Try setting the config option graphics win32_gdi and test it on the problematic machine. See below article for details on graphics settings. via config.pro.

The issue you’re encountering with Creo 6 on your Dell Precision 5680, specifically the error message indicating that an application has requested more GPU memory than is available, suggests a few potential areas to investigate:

1. GPU Memory Overload: The error implies that the GPU on your system is being overloaded. This could be due to the size of the STEP file you’re trying to open (500 MB is quite large) or due to other applications running simultaneously that are consuming GPU resources.
2. Graphics Driver Issue: The problem might be related to the graphics driver, particularly if it’s not up-to-date or not optimized for Creo 6. NVIDIA RTX A1000 is a capable card, but driver compatibility is crucial for optimal performance.
3. Open GL Driver: As you mentioned, this could be related to the Open GL driver. Creo Parametric relies heavily on OpenGL for rendering, and any incompatibility or issue with the OpenGL driver can cause such problems.
4. Comparison with Other Workstations: Since you mentioned that the STEP file opens fine on another workstation, it would be helpful to compare the hardware and software configurations of the two systems. Check if there are any significant differences in the graphics drivers, operating system updates, or Creo configurations.
5. Creo Configuration: The configuration of Creo Parametric itself can impact how it utilizes GPU resources. There might be settings within Creo that could be adjusted to reduce the load on the GPU, such as reducing the rendering quality or changing the way assemblies are loaded.
6. System Resources and Settings: Ensure that your system settings are optimized for performance. This includes checking the power settings, ensuring adequate cooling (to prevent thermal throttling), and closing unnecessary background applications.
7. Hardware Limitations: While your hardware seems quite capable, it’s also important to consider that very large and complex assemblies might inherently challenge the limits of the available hardware, especially the GPU memory.

To address this issue, consider the following steps:

• Update Graphics Drivers: Ensure that your NVIDIA drivers are up to date. You can download the latest drivers from NVIDIA’s website.
• Compare System Configurations: Check the differences in hardware and software configurations between your Dell Precision 5680 and the other workstation where the file opens without issues.
• Adjust Creo Graphics Settings: Explore the graphics settings within Creo to see if reducing the rendering quality or changing how assemblies are loaded can mitigate the issue.
