My solution to dx11 crashing

[nu1x]

So I solved timed dx11 crashes which were happening from 1 min to a few mins into the game.
The thing is, I have my 7900 XTX very slightly undervolted and overclocked; and it passes any stress test and never crashed in any other game. But you get the idea - BG3 Hotfix 1 seems to be more demanding than the most intense stress test.
I found out that the game runs stable IF I undo my slight undervolt to something approximating normal voltage (1.070) and my clock to way below even conservative and safe settings - 2300 MHz. I mean, even by default this card runs higher - but it crashes under BG3.
So Sapphire Pulse 7900 XTX - 2300 (Max) MHz GPU clock, 1.070 Volts, Default (not fast) memory timings, 2500 MHz memory clock (the minimum), 1.00 Power slider (default), and a great fan curve of course. This seems to work or at least works for a few hours which is good enough - no crashes so far.
I am playing with max ultra game graphical options and it's ok so far.
So there is something very specific to this game that drives the GPU mad.

Have the sapphire pulse 7900xtx and running into the same exact problem. Will report back when I’m home and try underclocking.

Also saphire pulse 7900 xtx, try turning v-sync off if you haven't. Played for a while with no crashes today v-sync off.

Have you tried capping the framerate to 60? 6900 xt here. Had a couple crashes on Vulkan, swapped to dx11 and never had a crash since.

[nu1x]

I always cap my framerate to monitor refresh, in my case 60. But haven't noticed vsync causing anything bad in my case at least, except the game looks worse without it in some scenes. Also on multi monitor setups I recommend turning off adaptive sync, it helped in other games at least.
Oh, and ALWAYS have your .NET updated by your Windows updates, learned that the hard way as Hogwarts was launching with old .NET versions, but crashing all the time. Updating just stopped all crashes.

This fixed it for me, have two PC's, exact same but one has 6700 XT and other 7900 XTX
7900 XTX has not crashed since this.
Thank you!

I tested it again and of the things I wrote above, the 2 main culprits (from driver setting point of view on my system, ymmv) seem to be undervolting and fast memory timings, setting timings to default and GPU voltage to 1.081 seems to work wonders for me. This game seems particularly weak to undervolting.
I mean, I was running my GPU just fine @ 1.035 for reference, but this game seems to crash at anything below 1.070 V (for me). So just increase voltage some more from that just to be safe. Factory default (1.150) is not even necessary, as it's usually too high anyway and just one-size fits all approach by the GPU manufacturer.
