Vray 5.2 gpu... Vram

[luisgamino2]

All right let me do that Muhhamed

Thanks
i found driver GeForce Game ready 496.49 WHQL is that ok that option Muhhamed??

[luisgamino2]

I installed that driver Muhhamed the newest and is the same, it doesnt render, only gives me a crash, i have been spending the whole morning just to render a scene... Everything fails for vray gpu, i'm tired about this, don't know what is happening

[luisgamino2]

I did a test in a very simple scene it renders but takes a Lot of vram with this new update

[luisgamino2]

Imposible to render a simple medium heavy scene, vray gpu light cache takes a Lot of vram, but a Lot, really a Lot

[luisgamino2]

As a feedback vray gpu needs a very special attention!!! Im going to return to update 1, vray gpu light cache doesnt work at all!!! Please fix that problem, i was so happy with the news today, then tried it and then it doesnt work, i am going to install the update 2 but when this feature is ready, probably a hotfix or something but Right now i can't use it, only gives me a serius crash.
Thanks

luisgamino2 If it crashes with BF/BF, then this is not about GPU LC or VRAM
Could you please upload me one of your scenes?

[luisgamino2]

I did a test with vray gpu bruteforce + bruteforce just with vray gpu, never with cpu i have a slow cpu i7 8700k, You can change from the ui to light cache to brute force
Vray gpu doesnt work with update 2, takes too much vram Muhhamed

[luisgamino2]

Im ready to send You a scene... Vray gpu doesnt work Even with light scene... Very disappointed with this update!!! I'm going back to update 1, i'm going to keep the update 1 for months Konstantin this seems a very heavy problem... 10 test no single 1 render... I'm loosing just My time, and vray works SO Nice...but vray gpu is another thing

We are looking into this now, and we have a fix in place. would it be possible to have one of your scenes, so we make sure it is not a different issue on your side

Best,

Hi Muhhamed
I Can send You a scene, but how does it work, i have never sent a scene to chaos group support, is not going to take a Lot of time? Or can be tedius? The scene i'm going to send You always worked with update 1, but update 2 didnt work, is a medium scene not really heavy, but You can see there that something is not quite right.

Thanks

Dear luisgamino2,

The best way to share files with us is via our contact form.
When it is a scene related issue (as in this case), please choose 3D and rendering help under Request type and mention this thread in the description.
In addition, please use V-Ray > Pack Scene - a standard approach to collect all the included assets.
The discussion here will continue thereafter.

One more thing that I want to note here:
We have identified an issue caused by the On-demand mipmapping option.
It can potentially cause the errors from one of the screenshots.

As a temporary workaround you can go back to Full-size textures.

Hi guys,

There is a new stable build uploaded here - https://nightlies.chaosgroup.com/mai...table/20211112
One GPU memory issue has been addressed.
Everyone who has observed excessive VRam usage can give it a go and see if it's any better.

Thank you in advance,
Konstantin
