Crashing on explosions

[XxSYNDROISxX]

i'm on level 5 of DF2 i believe and anytime i blow up something a drone or a mine the game crashes to desktop and i don't know what to do.

can anyone help me

[XxSYNDROISxX]

did you find a fix for MOTS?

Doesn't happen to me regularly, but explosions, esp. from grenades, do tend to crash both JK games on my system. I'm using Win11.

that's whats happening to me any explosion crashes me

[Swashbuckles]

Same here, it's unbelievably frustrating

This happened to me semi-regularly during my recent playthrough of JK. It only happened once or twice in MOTS. It was almost always just the exploding barrels that did it to me though. During one level it was happening more so I just started turning away when an explosion was about to happen.

About to start to play MOTS on the Deck, and whilst reading the game docs - by default I assume that old DOS games will have issues in newer systems, hence nothing like doing "homework" to level expectation and... it says there:

"Do not use Force Pull on the Heavy Explosives in Level 5. If you try to Force Pull the Heavy Explosives, when you pick them up they will not appear in your inventory and you will be unable to finish the level. If this should occur, load your last save game, and do not use Force Pull when you re-encounter the Heavy Explosives."

Don't think its a coincidence but definitely a known bug that they already knew but they never got around to fix?

P.S. will update this thread once I reach/pass level 5.

same for me on w11 on level 5 and 6, maybe on the others too

I'm having this problem as well. I'm noticing everyone's saying Windows 11, I've upgraded to it since I last played.

I'm having the same issue in Level 6. I literally can't get further because of all of the mines in the area. Every single mine CTD. Any suggestions on how to resolve this? Or am I just done?

[CaptainGeoluread]

I've looked into this further and noted that this wasn't happening the last time I played, which was relatively recently.

The key difference? I'm now running Win 11, not 10. I'm also running JK Remastered.

@The_spyder I found throwing detonators at the mines and quickly turning my back and running away helpful to get through the first bit of L6.

I noticed this only seems to happen on L6 and only with the sequencer charges and thermal detonators, NOT rail charges.

I've a theory (and it's only a theory): I remember when I used to use JKEdit that the Sith engine uses palettes for each locale in the game - that is, it's not drawing from one set of textures but from several different ones.

I wonder if whatever palette it is that Level 6 uses plus the explosion effects plus Win 11 (and presumably DirectX 12 Ultimate) is part of the problem. It doesn't explain why Level 8 is fine, which presumably uses the same texture set (unless the nighttime setting means it actually isn't the same).

[CaptainGeoluread]

Just to update you, I might be onto something here. I downloaded a custom level that uses the same assets (Siege at Derra IV) and ran into the same issue, this time whilst being attacked with a rail detonator.

Have finished DF2 and currently on DF2:MOTS (both wo mods), and have not encountered such issue. Windows+DirectX may indeed by the issue as suggested - as am using Proton w SteamOS and works just fine.

I have a saved game per level, so its straightforward to launch the game on my old Win10 laptop (5th gen Intel w HD4400, with DX12). Am happy to do it, if anyone share a specific moment/action where/how it happens (on level 6 for example)?

Update: yeah...now I remember why I gave up on Windows for retro-gaming. On my 5th gen intel wo dedicated GPU win10, the game now crashes when 3D acceleration is off, but with it on the screen goes black except the hud/crosshair (but you can play the game...blindfold mode difficulty)

On the daily driver an 8th gen intel w a dedicated GPU, game runs only wo 3D acceleration only at 320x240 but has no issues at level 6 - stepped on mines like crazy no issue there. But does not run at all with 3D acceleration on...

So... maybe 3D acceleration also plays a part (besides the GPU model)?
