I have a pretty long post on Reddit about this (https://www.reddit.com/r/avowed/comments/1istru9/fatal_error_a_rant/), but I wanted to bring it over here to the official forums as well.
TLDR: It took me 3 hours of troubleshooting to even launch the game, but now it's effectively unplayable due to graphical glitches and "fatal error" crashes. It's not my system, because I'm able to play games like WoW and Veilguard on max, and 3DMark gives me a high-percentile rating on my system (https://www.3dmark.com/3dm/126335795?).
I love Obsidian, and I'm excited for this game. But I'm about to do my first ever full refund with Steam because this is unplayable. Check out what the game looks like in the attached images. I have many more screenshots that are equally bonkers.
Here's my system: i7-13700 KF, RTX 4070 TI, 32 GB RAM, ASUS ROG STRIX Z790-E GAMING WIFI I. You can see all of this detail verified in the 3Dmark link I've posted.
Here's all the troubleshooting I've done:
BIOS update to address Intel issues.
Fully updated Nvidia drivers. Reinstalled them multiple times.
Ray tracing off.
NVidia input lag and upscaling off.
Frame limited to 60 fps.
Launched with -dx11 tag in Steam (always fatal crashes if I don't do this)
All graphical settings to Low.
I'm able to launch the game, and cutscenes play beautifully. But the actual gameplay is what's fcked. Once I got it to launch, I've been able to adjust graphics settings up and down and use basically all of them, but the errors just keep compounding. The textures look terrible, the bodies on the beach look comically bad, with bulging eyes that are uncanny valley. When I move the camera, faint square artifacts appear and the slowly fade, which effectively leaves afterimages as I move around. My character and the initial companion look great! Menus look great! But everything else is completely awful.
I doubt folks here can help crowdsource a solution; this feels like problems with Obsidian QA and code. But if anyone has further thoughts on troubleshooting, I'm open. But I don't feel great about spending hours of my life just to get a $90 triple-A game into a playable state. Studios are literally training me to wait a year to buy their titles when they release things in this state.
