The Talos Principle has a new stable build with more Vulkan optimizations

Quoting: SolitaryI think I experienced those black screen crashes, I don't know if they are the same, maybe they fixed those already, did you try SSH? Your machine actually might have still lived, because when I experience those freezes I can't jump into console either, I think it's because keyboard does not respond (classic numlock test), because Xorg is "busy", but SSH still works.

At that time I was not aware that it was possible to recover the system outside of ctrl + alt + f1 (my first crash of that kind since 6 years on GNU / Linux / Ubuntu probably ^^), and as the system was hard-locked I was not able to search online for a solution. ^^'

I used to have the black screen crashes, but haven't had them since the 375 driver.

Quoting: Purple Library GuyVulkan improvements. So, pointier ears?

That's next update, this one is less feels.

Now I got 30+ more FPS in average according to the built-in benchmark compared to earlier results. Neat. :D

Crashes here too, sometimes to desktop and sometimes freezes hard enough to need ssh help, logs are full of

00:31:32 INF:  Trying to allocate device optimal memory pool of X MB for Y KB object... failed! (0 MB of VRAM already allocated)
00:31:32 ERR:  Vulkan: Out of memory! (CreateSurface, allocate memory)

leading to the crash. There's graphics corruption too.

It seems to work with GPU memory setting set to lowest, but it's not exactly a pleasant experience with that - autodetect selects the memory setting as "High" for the card (Geforce 960, 2GB) and OpenGL renderer works fine with that.

(The old version was exactly same so I don't have any regressions in this regard, but alas no improvement either)

Quoting: SolitaryHard lock of the system with black screen, ctrl + alt + f1 was not responding... so hard reboot (which isn't a good idea, I've read that there is a more secure way to reboot the system... should note that somewhere for my next adventure in Vulkan's lands ^^)

Remember Alt + SysRq + REISUB (http://askubuntu.com/a/36717/31099)

To remember REISUB, you can either:

- Remember that it's BUSIER backwards
- Reboot Even If System Utterly Broken

This has been quite useful for me, especially when coding real-time kernel modules (and inevitably a bug freezing the whole system). It has also been useful when I was affected by a bug related to swap which made turning off super slow (minutes), so I could just turn off the computer safely and quickly.

Pay extra attention to the S (sync) and U (remount read-only) commands, as they are what really make the reboot safe.

Isn't it Ctrl+Alt+SysRq?

I personally used to remember it with "Raising Elephants Is Simply, Utterly, Boring"
Note that some SysRq must be activated before they work. And the kernel might be compiled without, IIRC.

I also like Ctrl+Alt+SysRq+ F

That calls the OOM killer, which will kill the process with the largest amount of memory. That's useful when a program makes the system unresponsive because of swapping.

Otherwise, I think a Ctrl+Alt+SysRq+R might give you back the ability to switch to a VT (that is, if your graphics card didn't completely lock-up).

Back on the topic, it's really nice to hear continued improvement on Vulkan games and drivers. I can't wait to have a Vulkan-capable graphics card \o/ (Vega, I'm waiting for you).

Read my comment, you forgot the "sync" part ^^

Quoting: M@yeulCIsn't it Ctrl+Alt+SysRq?

Nope, ctrl is not needed: https://en.m.wikipedia.org/wiki/Magic_SysRq_key
