after years of using Vantage is crashing on every project ...max 2025 and 2026 vantage_2.8.0-vantage_2.6.2

[linden_vennard]

Is there a way to test My gpu? maybe its broke or over heating
is there to completely re set the Gpu link ?
its not giving me a crash dump it just locks up

any help would be greatly appreciated

Are you the same guy from facebook that got his power cut off and then Vantage stopped working ?
In the logs you sent me, there is only one error and it's a failed allocation of a ~50 MBs texture.

Try the following (start Vantage or reload your scene after each step and check if it's working):

0. Turn off "Safe GPU allocations" in the Vantage preferences (before opening your scene).

1. Disable displacement in the Vantage preferences (before opening your scene).

2. Check your HDD/SSD drives for errors - right click on a drive in Explorer -> Properties -> Tools -> Check (then Scan).

3. Reinstall the nVidia driver.

4. Disconnect one of your monitors (I see you have two from the debug log in the e-mail you sent me).

5. Install an older nVidia driver that you know worked.

6. Delete everything from :
"C:/Users/{your_windows_user_name}/AppData/Local/NVIDIA/DXCache"
"C:/Users/{your_windows_user_name}/AppData/LocalLow/NVIDIA/DXCache"

7. Install GPU-Z and watch what's going on in the "Sensors" tab before the crash occurs (you can make a video (e.g. with ShareX) and send it to us).

8. Move the .vantage file associated with your .vrscene to some temporary location, i.e. start fresh from .vrscene without a .vantage file.

I'm rendering using Live link if that changes anyting

[linden_vennard]

Vantage was locking up the computer with i launched it ....so im going to try to revert the nVidia drivers

In that case, you can also try deleting your vantage.ini file from %appdata%/Chaos/Vantage

Ok
vantage.ini file from %appdata%/Chaos/Vantage
got things working ....file rendering @ 2 k but not 4

Bear in mind that after deleting vantage.ini, all your Vantage preferences are reset to their defaults.
So, you can again try turning off "Safe GPU allocations" and lowering the displacement settings before attempting to render at 4K.

Exporting to .vrscene, closing 3dsMax and then opening the .vrscene in Vantage can also save you some GPU memory (compared to rendering though the live link).
You can also try disabling some render elements you might not need.

I dont think its a size issue i can crash my system with a simple test file...something got corrupt in the last day ...ive been using vantage with no issue for a week 1000 of renderings and now it just crashes...

[linden_vennard]

also my IPR using Vray CPU is crashing to ...im not sure if that's related

[vladimir.nedev]

Did you try an older nVidia driver and the rest of the things I suggested ?

Maybe you should attempt a Window restore.
No idea what else could be done beside a full reinstall of the system.

Another thing you can try is to disconnect your PC from the wall socket, wait a few minutes and turn it back on.
Sometimes a capacitor can get stuck when a quick power outage occurs.

The dmp files you sent me are crashes at a few different locations in the code.
However, they are very similar - Vantage is trying to write to a shared GPU memory buffer, i.e. that's CPU RAM visible to the GPU, not VRAM.
It looks like the buffer couldn't be mapped for writing.
I have no idea how this can happen, whether it's a driver issue or an OS issue or a hardware issue or maybe the driver crashed before that.

You shouldn't rule out a hardware issue.
If you have a spare GPU, you can try replacing the 4090 with it for a test.
Other options are to reseat your CPU memory modules and the GPU itself (if you are comfortable doing that on your own).

thanks so much Vladimir for helping me
