Regarding the startup crashes on Intel integrated graphics: As far as I know we have still not been able to reproduce them internally. I could for example start the client successfully (and with ok-ish frame rate) on a machine with the same (or at least very similar) Intel chip as one of the reports, so yeah…
We had also one reporter, who mentioned that he could not start the client in dx11 mode, but he code start it in dx9 mode, but with horrible frame rate.
If you are affected by this: Please send bug reports with logs from logLite and with as much information about your machine (laptop) as possible. Maybe this is only happening for a specific brand of laptops, but we are missing this data so far.
It would also be great, if you could try to start the client with completely clear cache and settings - just for the case that anything happened there.
