Render in GPU takes too long to start

[damiano_corradini]

Hi,
when i start a simple low quality render in GPU it takes about 5/8 minutes to start (staying on "loading bitmaps").
If i render in CPU it starts really fast.
I have the last version of V-Ray and Sketchup.
Here is the benchmark and the link for download pack project of the file.

Hello damiano_corradini,
Thank you for your scene.

V-Ray Benchmark scores for your GPU are expected, thank you for testing it.
I do not reproduce such long times loading bitmaps with your scene and latest V-Ray build 6.20.01. On my screenshot you can see elapsed times for actual render and times compare it with times that it took overall.



From the Benchmark screenshot I see that you have 546.33 drivers installed at the moment. Could you please install the recommended version which you can find on the top of this page: https://www.chaos.com/vray-gpu. This version is tested and approved by V-Ray developers and how it works with V-Ray, so it can be different from the latest version released by NVIDIA. In this forum post you can find steps to install drivers in order to have best performance with V-Ray GPU: Installing the recommended Windows Drivers for V-Ray GPU on Windows. Please follow these steps and test your scene once again.

Also, let me know where do you store textures? Please share a screenshot of Extensions > V-Ray > File Path Editor. As a test you can try to Repath all of your textures to some local folder for example on Desktop, will this make any difference?

Let me know the results.

Thanks a lot, the issue disappeared from the moment i installed the correct driver version.
