Hallo to FC community, 
I am having problems when trying to run Penumbra Overture on Linux.
(Arch 64Bit, but I do have 32bit libs installed).
I'm trying to run it on HP Pavilion DM4 50ea laptop - Intel HD GPU. 
Not sure if this GPU is supported, but acceleration is working fine with i915 driver, so it should work.  
My HPL1 log follows;

Now, there are some errors in there, but I'm not sure what to do about them, so any help will be much  appreciated.
