Vray underusing GPUs?

[archean_light]

Does the GPU performance monitor in task manager accurately reflect Vray's usage?

See screenshot, GPU 0 runs around 25%, and GPU 1 1% - this is the case when rendering locally and via deadline.

Latest version of vray and max.

Use the dropdown to choose the right graph - Compute. Anyway I would recommend using some 3rd party software like MSI AfterBurner or EVGA Precision. We have our own statistics in the VFB as well.

im having a similar issue here, i only get about 25% of the GPU's (6xGTX1080ti) capacity used.

i have installed the 419.17 nividia driver.

And have you read my post above?

when i set the dropdown on "Compute_0" it shows no activity, when i set it on "Cuda" it shows a usage around 25%.
i guess u supose i should have a try with some third party software then to monitor the graphicscards usage.

i'm having a gpu setup with a Biostar tb250-btc motherboard, which is originaly meant for mining. could there be any reason this setting could cause some slowdown?
also i have only 8gb of ram (which i gonne increase very soon).

So those cards have 11 GB VRAM and that 8 GB system RAM is definitely a showstopper for any kind of meaningful gpu rendering. Also it is strongly recommended to pack a relatively powerful CPU (i7 f.e.) for multi GPU setups.

ok, thank you for your advice. i increase the ram, and have a look how it performs.
so mybe i get a faster cpu then aswell.
thank you Peter!
