Yes, definitely check out the release notes before reporting issues:http://www.planetside.co.uk/forums/index.php/topic,21732.0.html
But thank you all for your feedback so far, very helpful!
TG4 does use more memory than TG3. It should *not* cause blue screens, in fact it should not be *able* to cause blue screens *unless there is something else not quite right in your system*. That, at least, is my understanding. With Win 7 and even more so with Win 10, the protections in place for memory allocation, driver handling, etc. should really minimize blue screens for any software that is not doing anything hardcore and deep with the hardware (which TG is not).
So it's possible that the higher memory use of TG4 is exposing existing but previously unseen issues in your memory, as one example. I have actually seen myself on an older system a case where I had a fairly large amount of memory (for the time) at 16GB and I was seldom using all of it, and it turned out that some part of the memory that was always allocated as the higher blocks (i.e. closer to the 16GB limit) had some corruption issues. So to put it simply, I would see crashes but only when the memory was almost fully used. I was able to use a memory tester (memtest86+) to test all of my memory and find the issue and then get my memory replaced under warranty. So this is definitely something worth looking into.
If you have more detail on the message(s) that came with the blue screen that would also be helpful. It could be related graphics card driver issues, for another example. But it's hard to say without a bit more info.
Overall TG4 should not be causing blue screens. I don't know if anyone else has seen any but I certainly haven't in many months of testing. Plenty of crashes, yes, and this is somewhat to be expected while it is still in beta, but these crashes should not take down your entire system.
