Played without issue for four months. Now, same PC, new GPU, and I can't log in P99

[Agreed]

My specs are Intel 12900K CPU, 64GB VRAM, and AMD 9070 XT card. Previously I used an nVidia 3080 12GB, swapped to the new card and now I can't log in to P99. When I select the P99 blue server and hit Enter or click "Play Everquest," the client just freezes for a bit and then kicks me back to the first login screen.

This is happening with WinEQ, and I've tried installing DGVoodoo to use the default EQgame client as well, happening there too. I tried making it use my Intel on-board GPU, which is way weaker than the 9070 XT is (or the 3080 12GB was), no change. I've tried limiting to just my Efficiency cores, no change. I cannot join the P99 Blue server no matter how I try.

I had a lot of fun playing this over the years, and in the last few months I doubled down on the grind and got my monk to a higher level than I ever did before, got a Fungi Tunic and a Tranquil Staff and a bunch of other gear upgrades from grinding Highkeep like a madman. Now I can't play at all it would seem and all that feels like more of a "waste of time" than just gaming usually is, I was thinking I'd be rocking with my guild raiding soon.

Anyone have any ideas of what I might try to get logged in once more and playing? I don't understand how changing to an AMD GPU could cause this problem or what I can try to do to resolve it. Thanks if you have a notion.

[Agreed]

Oh, I wanted to add, the only other issue I have seen that looks like this is the one AMD CPU users had where the CPU was, uh, too fast for EQ basically and had to be locked to a lower multiplier. But I've been using the same CPU to log in and haven't changed anything at all there, just swapped GPUs and did the whole DDU safe mode uninstall of the old ones, GPU is working great in every other game.

I'm trying to see if I can set up a virtual machine environment to run EQ from instead, I've read that can help with issues, but if anyone has a suggestion as to what might be going on here so I don't have to try workarounds I would really appreciate it!

[Agreed]

I resolved the issue, and here is how:

1. Went into BIOS and changed primary display to PCIE rather than IGPU

2. In BIOS, turned on Multi-Monitor IGPU mode

3. Allocated 512MB of RAM to IGPU, up from default 64MB

I can't understand how any of these things would have helped it but it works now. Unruly machine spirits within my PC, quiet now, perhaps.

[Reiwa]

That doesn't sound good. I think the I stands for internal GPU.
