Hello, I am looking into loading some missing Vulcan extensions onto my GPU (GTX 1660ti) that I know have been supported in the past. Here is my situation:
I have the latest drivers for my GPU (version 566.36.0.0), but I am missing VK_KHR_ray_query. I have looked at the history of support for this extension for my device and have found that it was included in driver version 460.89. However, this version is then missing VK_KHR_dynamic_rendering, which I also need, but this is present in my current driver.
I don’t know very much about drivers and how these extensions are loaded, but from what I understand, my GPU has previously had support for both of these extensions separately, but not together. Why is that and is it possible for me to somehow install the ray_query extension now?
Thank you all very much for your help and information.
This should deserve more attenction and a fix from Nvidia itself, usual d**k move to limit older GPUs. There are games like Indiana Jones and the upcoming new Doom that could run on our gpus if the supported dx12 but won’t on Vulkan because of this likely intentional omission, can somebody clarify why? Or please make ourselves be heard so that we can get a solution to avoid futile obsolescence
nvidia is not obligated to support extensions that were only implemented in a limited fall back capacity, for those initially developing RT capable vulkan applications in 2018.
The 1660ti cannot run this game at an enjoyable framerate by any means, as you are looking at 1-5FPS max.
just missing software rt for that faint global illumination that can be done on dx12, just not on vulkan since Nvidia did not implement the extensions above
