The Talos Principle updated again, new public beta improves their Vulkan support some more

This is great i haven't yet done a Talos Principle Vulkan MESA-Git video on my RX 480 tests

I'll be sure to use the new beta when I do, thanks for the turn on.

With the Vulkan renderer, performance was almost instantly at DX11 levels. So very good for Linux users. Unfortunately, it's also very unstable for me (hard lock ups). From what I've seen on the beta threads, this instability is specific to the GTX970. Any others here have the same experience?

Great game, and I want to finish the story. But I just get too queasy to play after five-ten minutes :(

I had the same with their engine. Could halfly fix it with these settings:
Graphics options => FOV 100
Game options => Bobbing off
Performance => GPU Speed => Zoom blur and soft-focus to off
(All back translated from German, wording may vary.)

I had similar lockups with a GTX 780.

Try changing the FOV to match your resolution. By default its set too low and gives some ppl motion sickness. I'd go no lower than 85. Bump it up till you get something comfortable for you.

I've tried all of these. Unfortunately it doesn't help.

A big part is learned expectation. In the beginning I played for 1-2 hours straight. But now my brain associates the game with nausea, so even if I change the parameters I now start feeling a little sick just by seeing the initial screen.

And it's such a good game too :-(

I was able to overcome it in Serious Sam 3, but I know what you mean.

Unfortunately, I cannot object...

Same for me. I never experienced motion sickness in any game until this one, after 10-15mn my eyes hurt and I felt sick. I tried all stuff related to FOV as those ones stated above, but none of them worked.

Finally I changed camera from FPS to TPS (camera view "over shoulder" in motion sickness options) and then I never felt sick anymore. I think it's because this game has no HUD or any fixed stuff on screen, thus leading my brain to get fouled. Switching to TPS made my character fixed on screen, and now my brain understands it's just a screen and not reality. I also reduced move speed and mouse speed.

BTW great game!

New features:
- Added support for latest ATi and nVidia cards.

What does this mean?
I thought Vulkan, done right, should not require such quirks.

@ stan

Try this in game launch options
%command% +gfx_strAPI "VLK"

Actually I'd assume they do mean they checked back things are working. Or maybe some additional features are enabled for newer gen cards? Unless that's the case I thought the same as you do.


EDIT: In addition, you wouldn't need to modify the drivers to much for every single GPU. Still the game devs have a closer connection to the actual hardware now.

The game froze badly enough for me that I couldn't access the CLI to end the game's process(had to hard reset my PC), and I'm using a GTX 1080 so it doesn't seem to be GPU specific.

What's going on with Croteam games by the way? Why don't they sell them on GOG (besides two old Serious Sam games)?

Still fails to switch to Vulkan… When I select the Vulkan API then Apply, the screen stays black and then the game reverts to OpenGL. So I have to Alt-F4 when the screen is black (at the moment the mouse pointer reappears), restart the game, reselect the correct performance settings, Alt-F4 again, and THEN the game is in Vulkan mode with the correct settings.

Benchmark in Ultra/Ultra/Ultra/Ultra on my GTX 1060 + i5 4690K in 1920×1200:
OpenGL: 62.2 FPS
Vulkan: 81.3 FPS (+30.7%)

I ran each test twice so that the game could cache stuff the first time and each second round was a bit faster than the first one.

I had +60% the last time I tried but that was maybe with different settings.

Huge improve, thanks for the test, in pair with DX12 performance now.

dx11 is still faster on the benchmark, and I tried to play a bit using vulkan and the game crashed. But this was on w10, on linux I cant use it since its an optimus laptop

Are you on 375.10 Nvidia drivers? I used to have this issue but with everything updated now I can switch back and forth in the menu without issue.

Here's what the devs had to say about this: [url=steamcommunity.com/app/257510/discussions/0/626329186809171707/]steamworks alternative + having to support an additional build[/url].

Although their supporting linux kinda collides with the latter :S. I was hoping I'd be able to get talos' sequel from gog, but then I found the link posted above.

So, this is the publictesting branch in Steam? Is it safe to switch to that with current saves on the main branch?

And 645M.

I tried the new build and it froze in a couple of minutes. In that couple of minutes the performance was rock solid though.

Yes, but you may not be able to switch back with the same savegames.
