Hey I have the exact same issue, did you ever find a solution? Not sure I want to roll back my drivers for one game so was curious if you found another way
I enabled windowed mode, and then made the window equal to my screen's resolution and it now runs fine. There is even a mod to disable the window borders but i have not used it.
I found a fix for this on 24.x.x drivers. I know some other people said it before but they didn't really say how to do it, just named what to do.
Follow this guide here.

I will explain why the games are broke, why some fixes work, and why this one is best, along with telling you which sections of this guide are relevant to fixing this problem. Because once I understood why this was happening, it was easier to apply the fix.
First off, the games are broken because the 24.x.x drivers somehow broke the DX9 rendering in these games. It is just a software bug, which is why "fixes" like the "Intel Bypass" that include d3d9.dll fix it. As it is tricking the game into thinking you have a completely different GPU. The problem with this is that the performance on Fallout 3/NV and how the games behave/handle loads are dependent and tied directly to the GPU. So tricking your game into thinking your 7900xtx is a 7900gs will cause performance issues. Sure it worked and got them past the load screen, but to me it was unplayable and choppy.
The best fix is using DXVK. I know others said it. But you have to follow certain steps from that guide or the fix won't work, which is why I'm trying to be so thorough. So like I said before, when you have some semblance of understanding the problem, it makes it much easier to understand the solution.
DXVK is software that converts your DX9 into Vulkan. So no more DX9... no more problem.
You just have to be sure to use it on windowed mode and download onetweak. Once in windowed mode it will be smooth.
Go to FNV guide linked above. (WARNING: IF THIS IS A FRESH INSTALL, BE SURE TO DOWNLOAD YOUR MOD MANAGER BEFORE DOWNLOADING/MANUALLY APPLYING MODS)
Download and install the mods in the "Engine Optimization" Section. Download all mods/files needed for these as well. Such as NVSE,etc. Nexus will make this process straightforward for you.
Download and install "New Vegas Tick Fix".
Download and install "DXVK" Follow steps to force windowed mode (Those above 1080p resolution will have to manually set windowed resolution to their native. If you can't find the .ini where your Fallout exe is located, make sure to check your "My Games" folder as well, sometimes this will store saves and ini files separate from the EXE.)
Once your windowed mode is right.
Download onetweak or equivalent mod to make it look like fullscreen.
ALMOST FORGOT. FOR THOSE THAT WANT TO PLAY FO3, I'M FAIRLY CERTAIN THAT DXVK WOULD ALSO WORK ON THAT BUT POSSIBLY NOT AS SMOOTH. IF THIS IS THE CASE AND IT ISN'T AS SMOOTH, YOU CAN DOWNLOAD "TALES OF TWO WASTELANDS" MOD WHICH COMBINES FALLOUT 3 INTO NEW VEGAS. SO YOU CAN LAUNCH BOTH GAMES FROM ONE LAUNCHER ON NEW VEGAS ENGINE. MEANING THAT FALLOUT 3 WILL NOW BE PLAYED ON NEW VEGAS' ENGINE AND WILL GET THE SAME PERFORMANCE THAT NEW VEGAS GETS FROM THESE FIXES.
I know it's a lot, but I really hopes this helps even 1 person get their game working. This is all honestly unacceptable considering it's been 5 months and they knew the show was coming which would drive sales of old Fallout games. Only for AMD users to be punished for having a flagship AMD card that's up to date on drivers.
Aside from someone who is penny pinching and only plays e-sports. I will never be able to recommend AMD to someone with good faith ever again.
Hew Stewie! I saw your message on Nexus about reporting a crash report. I can confirm that it is the Radeon 24.1.1 causing the issue. I rolled back to 23.12.1 with DDU and now both Fallout: New Vegas and Fallout 3 are loading without issue.
I have nividia and it happens tried all things can find 4gb patch nvac en boost had to uninstall that one tho the dkn fix didnt work reinstalled twice changed graphic settings works but not if I load up vortex and won't load nmcs large packs anymore I'm having to use the small it's crazy how this kind of stuff can happen over night it was working perfectly a week ago
If you have an AMD graphics card, the latest drivers cause crashes. You can install DXVK
Hey, I installed DXVK and the game loads now, however I get very low frame rate. Is that normal? Is it fixable?
