Radeon Exception_access_violation

**EDIT.... Not a Leadwerks problem, but it did help me identify it.

 

Finally decided to give Leadwerks another go (the new tree painting features are looking awesome) and have run into what I assume is the Radeon driver issue (again). Cannot even start Leadwerks, goes straight to the error "Exception_access_violation"

 

Just thought I'd post the details of my driver here.

 

Have tried the latest beta (29-Nov-2015) and the current "release" version. Same error, so I am pretty comfortable is stating that AMD has broken something again for me.

Thought I'd update everyone. (edited original post as it implied that this was a Leadwerks error....which it is most definitely not)

 

Tried some other OpenGL apps and found that they we also failing, it looks like some were running happily off the Intel HD4600, It depended n what I was using...oddly one that confirmed it was Virtualbox...

 

So it would appear in my case (an Intel/AMD Radeon laptop config), that 15.11 Crimson is not going to work.

 

Steps for this were.

removed intel and AMD drivers, and reinstalled the latest for both, go the same result

removed the AMD drivers (so just intel 4600HD running now), works like a charm again

reinstall latest AMD (redownloaded) 15.11. failed again

magically find a copy of the old 15.3 Beta drivers (Josh recommended the last time AMD messed up) .. Works perfectly now.

 

So note to self, never, ever, ever update from the 15.3 Beta drivers....and same up some money to replace card with an Nvidia (this laptop has a replaceable GPU)
