Now, since latest dev-blog recommends switching to DX12, I believe this issue needs some more attention. In nutshell: if you quit one of 2 currently open EVE Online windows (both omega ofc) while you use DX12, the PC will freeze till next GPU adapter re-init. For trolls: this has been reproduced on 2 fully different PCs, with 5 minute fresh Windows 11 install. This also has been reported and even escalated to the seniors (requests 2187728 and 2175590). So, the DX12 is not playable when multiboxing, I should keep my launcher to use DX11 . Issue is not mine alone, similar people are reporting the same behavior across multiple sources: > **[Reddit - Dive into anything](https://www.reddit.com/r/Eve/comments/18oi4b4/client_freeze_while_multiboxing/?rdt=43827)** > [@Multiboxing and screen freezing](https://forums.eveonline.com/t/multiboxing-and-screen-freezing/373843): > > I’m running multiple monitors with multiple clients. Most of the time my clients run without issues, my cpu/memory/gpu utilization levels stay in the 50-70% range and everything runs smoothly regardless of what I’m doing in game. Sometimes however, one client on a random monitor will go black or freeze, the game still responds to clicking (ie: if I double click in space it’ll move and if I click the right spot where a module will be it’ll activate, etc) but I can’t see anything. If it’s frozen,… And many more (will post more in comments) So what I can conclude - I just reproduced the freeze today with DX12 on 23H2, 12th Gen Intel(R) Core™ i9-12900K 3.20 GHz, 64,0 GB (63,7 GB usable), 3080 Ti. Please, CCP, we cannot use you’re recommended settings. Investigate please. ---

Similar issues: > [@Second Gameclient freeze after quiting the first](https://forums.eveonline.com/t/second-gameclient-freeze-after-quiting-the-first/395686): > > Hello, im running two clients. Every time i quit one (dosnt matter first or second) the other client freeze the video (sound runs in background even the game itslef seems to run - like docking progress still happend ect.) and AMD driver crashes - causing it sometimes to recover the client to normal state. Any idea how to fix that ? > [@Can't play Eve with multiple clients since updating to Windows 11.

I’m experiencing three main issues, and here they are ranked from most problematic to least: One of the clients will reliably have it’s UI completely freeze after a few minutes of playing the game. I can still hear Client sounds when I move my mouse around, so it seems like the client is still getting some input, but the UI will freeze completely, and nothing I do seems to unfreeze it until I clos… And more, just no point putting them all here. They all are fixed by switching to DX11. ---

Actually. I just found out that disabling V-Sync on all windows did help. ---

I FYNALLY GOT IT! Disabling “Windows (11) Security \> Device Security \> Core Isolation \> Memory Integrity” fixed it. No more freezes on DX12! FINALLY! FINALLY! ---
