How can you make the scene load on to the GPU's VRAM faster?

Ok so the goal is to start the render quicker. Although GPU rendering is much quicker, it is annoying to click render, wait 10 seconds and then start to see the actual progress - especially if you are making tons of the small tweaks. RT is great, but only at small resolutions. What hardware or adjustments can reduce this buffering time? I heard that GI light cache is only CPU capable, but would that mean it's single threaded? Would a higher clock or more cores speed things up? Thanks!

RT is great at any resolution!

Higher clock speed is Yes 100%
in some Vray plugins, using proxies or static meshes makes this translation faster as well.

for GPU IPR, it doesn't use LC at all.. Only production rendering can

Thanks for the response! But what about core count?

[Muhammed_Hamed]

Core count won't benefit this case at all, Octane uses only 4 cores when GPUs are under load
Vray uses few cores as well. Higher frequency will make your GPUs perform better out of box and it will benefit scene translation.

what kind of v-ray plugins would benefit from static or vray proxy? i have a gigantic model here (doing a set extension). vray proxy seems to yield faster GPU results, but i've noticed that it doesnt cache textures between renders as it seems to do between production/CPU renders (output window shows it is pulling the 10 GB of UDIM files off the server every time i render a frame). this happens when i use CPU as the IPR engine as well. (using v-ray 3.6 and maya 201.

do you have any general advice for speeding up GPU previews?

thanks!

Using this in Vray for Maya and Vray for Modo, it helps quite a lot when you have millions of polygons. In your case, you have a lot of textures as well. I don't know if there is a way of keeping this data in memory so you don't have to load them every time you start the IPR
My advice is to upgrade to Vray Next if possible, which has a completely redesigned IPR. It is much much faster than 3.6 IPR, specifically starting or stopping it should be quicker out of box.
