purge gpu memory between renders?

[s_gru]

hello. using gpu, vray 6+, max 2024. is there a way to purge memory from a gpu without closing and reopening 3ds max. for example,

After IPR render: Showing 10GB steady
Before IPR rendering of any sort, freshly opened scene: Showing 6GB steady
3ds Max Closed, nothing else open: Showing 1GB steady

This is 2 RTX 4080s, the one I'm quoting for memory used is 1 of the cards with the two monitors connected. Max2024 & Vray6+ GPU renderer.

Is that a 3ds Max thing?

Thanks,

Go to user/profilename/appdata/local/temp and delete all the files. You'll get a message for some saying unable to delete, just select apply to all and select skip. Should clear some of the cache. Works for me.
