They likely won't have support for the new RT core features of Blackwell for a while though if any are relevant... I think SER for Ada was added around a year and a half after the cards came out, and for me on a 4090 anyway it made renders roughly 2-3x faster as SideFX said it would so it was worth the wait... part of the issue is that NVidia loves releasing cards that technically have the features then taking their time adding them to drivers and libraries, although I'd argue that this is better than AMD's strategy of having hardware features that never get enabled (the geometry shader cores on Vega, for example) or disabling features that worked when the card came out (1/2 speed fp64 on Vega7 being lowered to something like 1/32 speed, for example).
Ada still has no library support for TransformerEngine on windows for example, although that only affects quantized inference of ML models which isn't as big a deal for most of the image related ones... the people training and running LLMs, or as things are turning out in reality, "new-school spammers" as I like to call them (if I'm not saying what I really think which is unprintable in most states), are the main group affected by that on ada and blackwell and they'll just run linux. It may affect Houdini down the line if some very useful generative 3D models that 8 and 4-bit float quantization can be used with show up but I'm not holding my breath.

The Shader Execution Reordering(SER) update was great for the 4090 cards. We got around x4 speed increase on renders with fur compared to 3090 cards.

If someone wonders, the 5090 cards have been stable so far for us.

Hi Heileif,

May i kindly ask, which drivers version are you using? also studio or gameready?
