Your GPU is too old to meet the requirements for Houdini.
Additionally, it appears the app needs a workstation level GPU, not a consumer Radeon product.
Catalyst was the name of the driver for older product. Currently supported products use the Crimson driver.
Thank you for your reply. It is true my card is not in the official suported list. But first houdini DOES work on it, but something is wrong. I mean the software loads up, with no error message. I can do stuff in it for 1 minute or 2 sometimes, some times even more like 10 minutes (this happen only once). Andm anyway my card used to be able to run houdini 2 years ago, when i had a windows 8 and that period Catalys. Meanwhile the Catalyst software updated some software, windows also made some updates and bang, it doesn't work anymore.
I really, really don't think that is the reason. I tried running houdini without the card drivers, and it doesn't start. It gives a message that it needs a OpenGL 3.3 compliant driver. After install the latest catalyst or Crimson drivers, Houdini opens without any glitch, it works smooth and perfectly until some conflict happens somewhere and it resets the video card and hangs Houdini.
If AMD Radeon HD 5450 wouldn't be able to run it, it simply wouldn't start. But this is not it.
I think the difference between Catalyst and Crimson might have something to do with WHQL .... i'm not sure, i seem to not be able to find a simple description in the whole internet of what is the difference between those 2 software....
Does anyone has this issue with houdini 16 ?
