Well, I've downloaded and installed the very latest versions of everything. I am still having the problem, only now I get to the loading screen for the second level before the game crashes. I'm still getting the "memory access violation" notice in the d2x.log file. I posted the log on sourceforge support request page a few days ago, but I'm not getting an answer from there so I decided to post back in this forum too.

Do you understand enough of programming to install MS Visual Studio Express 2008 and the source code required to build D2X-XL and build and debug a debug executable of the program?

Hey Yoshimitsu, just a thought here. I assume you are currently using Hires models or textures yes? (you mentioned using ASE format hires models before)

If so, have you tried disabling them using the ini file and just used the default Descent content instead?

I my previous experiences, alot of memory access violations occur during the process of loading hires models/textures between levels.

Oh and if noone responds to you on sourceforge just be patient, it doesnt mean noone got the message

Thanks for the thoughts, both of you.

Unfortunately I don't know anything about programming, Karx11erx. At least, not as far as I know. There might be things that I do that are programming, that I don't label as such For now though I'm strictly an end user.

Yes, Yokelassence, I am using all of the hires options. I will try turning them off, but I don't think they are the issue. In the d2x.log, the memory access violation occurred during "building terrain light map" so I'll shut lightmaps off first, before disabling the textures and models.

Just so it's out there, I've been using level one of Descent 1 for my tests, but I do get similar results with Descent 2 Levels.

Finally it works.

I went into the D2X.ini and turned off all of the cache on disk options, and per pixel lighting. this seems to have stopped my issue of between level crashes.

Thank you everyone who has offered their help and advice. :D

Yoshimitsu,

I think it must be either data caching or per pixel lighting. Please turn on PP lighting and check whether D2X-XL crashes again for you then. If not, try to turn on caching, delete the entire contents of the cache folder and see whether D2X-XL starts crashing when playing the same two successive levels of some Descent mission (you need to play them too times as during the first time the data will be computed and stored in the cache folder, and during the second time that data will simply be loaded from the cache folder).

If you are using hires textures with the highest texture quality, decrease texture quality unless you have a graphics card with at least 512 MB and better 896-1024 MB RAM.

I can't quite understand what you mean about testing the data caching. I'll put down a sequence of events that I think you mean.

1. turn on caching
2. delete the contents of the cache folder
3. start the game and play through 2 successive levels
4 close the game and restart it.
5. play through the same two levels and see if the game crashes

Let me know if this is right.

Per Pixel Lighting works perfectly.

I've finally gotten around to testing out the Data Caching. I used the process we described karx11erx, and the game still plays fine. the crashes haven't happened again. Maybe I just had corrupt data cached the first time I started the game.

I'm still using all of the texture, sound, and effect settings on their maximum level and aside from a couple of glitches in descent 1, everything runs smoothly.

Yeah, that's what I think too. Thank you.
