The bug has been identified. The game asks the GPU video from the wrong GPU on systems with multiple GPUs. As Intel's integrated GPU has no dedicated memory, the game incorrectly assumes there's no memory to store the textures, and this causes breaks texture streaming. Fix for this bug is already in testing. We will include it in the next patch.
Thought I might add to this thread.
I've taken my 780 ti out of my rig to be sent back for a new one, and I'm now using the Intel 4600 integrated graphics. When loading the game it starts in a weird resolution, and in the settings I can't change the resolution any higher than 1440x576.
When playing I get the weird textures, slow-mo gameplay at around 47 fps, which most people are encountering. I'll add that my computer is a Desktop not a laptop
Hope this helps in some way.
Current rig:
Intel core i7 4770k
Asus Hero Mobo
8gb ram
This information from sebastianaalton was over at the No 1080p thread and should clear up some info here:
"There were THREE bugs that caused these issues. We only fixed one of them in the Friday's patch. Fixes for the remaining two will be in the forthcoming patch.
1. Game detects GPU memory size incorrectly if multiple GPUs are present. Integrated GPU has no dedicated memory, so our texture streaming system gets broken.
2. Intel integrated GPUs have additional texture corruption bug caused by GPU floating point rounding issue.
3. On NVIDIA Optimus laptops (integrated GPU + GeForce) the wrong GPU was selected.
We fixed number 3 in the patch. The frame rate is now 60 fps in the game, and you have helped me with NVIDIA Inspector to prove that the GeForce GPU is actually used. Bug 2 doesn't affect Optimus laptops, but bug 1 certainly does. This causes the textures to be corrupted also on the GeForce (and limit the resolution to 720p). We will fix bugs 1 & 2 in the forthcoming patch."
I'll repost what I said in the other topic, hoping it will get to Seb's ears this time and maybe others can run the sametest and post their feedback.
Once again, bug 3 is not fixed by the patch as far as I'm concernedYou may want to double-check if bug 3 (Optimus) is really fixed Seb
As of today, If i go to my Nvidia Control Panel, put everything on auto-select, then go on program settings and add the trialsfusion.exe, it still says the following :
Use Global Setting (Auto-Select: Integrated)
Maybe others in the same situation could do the same test and confirm it, but that's how it looks on my hand![]()
