I've been having issues with Fallout 1 since I downloaded it the other day. The first time I ran it, it ran fine, but now the screen goes black at the menu or, if I restart the computer, it goes black about five minutes after I start the game. Wherever the cursor goes it comes back.. for a moment.. and then it goes black again. I've tried 98/ME compat and turning off compatibility mode, so.. I don't know what to do. It worked the whole two plus hours I played it when I first got it.
Any advice?
To quote Odin from No Mutants Allowed:
Blackouts under XP
------------------
If they only happen infrequently, you might consider ignoring the problem. If you bring a new screen with the 'C' or 'P' key and close it again, it will have wiped the blackness off the screen. This can reduce the problem to a minor nuisance.
OK, let me clarify things once and for all for those who are having problems launching the game or having blackouts in the game under Windows XP. Now, there is a workaround thats gonna cause a bit of inconvenience but it works for many old games including Fallout 1&2.
There is an option in XP in your hardware>device manager that allows you to disable your video card - do it! (dont worry, you will still be getting descent graphics), then restart your computer, close all your background programs on the taskbar(optional) and voila!
Note: This solution was tested only for ATI Radeon 6500 and 9000.
Also, if you need any patches(like "children fix" for UK version), some info or tweaks then check this site (http://www.teamx.ru/eng/files/utils/index.shtml)
I found this great article on how to optimize Windows XP by trimming some fats off it Check it out, Its a life-saver (http://www.3dluvr.com/content/article/123)
You can try turning down the amount of hardware acceleration on your computer, which can be found at Desktop -> Properties -> Settings -> Advanced -> Troubleshoot. Try different settings on the hardware acceleration slider and see how they work.
Another thing you can try is adjusting the priority of the Fallout process. To do this, alt+tab (if this doesn't work, skip this step and just press ctrl+alt+del, which should minimize the game and bring up the Task Manager anyway) out of the game while it is running and press ctrl+alt+del. In the Windows Task Manager, click on the Processes tab and find the Fallout process, it will have 'Fallout' in the name. Right click on the process and choose "Set Priority" adjust this and see what effect it has on the game.
You can also try what helped a previous user by the name of duc:
Disable AGP Fast Writes in the System bios:
this is usually under chip set or PCI settings.
Disable AGP Write Combining:
For the Latest Nvidia Forceware Drivers this is under display properties -> settings tab -> advanced -> troubleshooting
and may only show up under certain hardware / driver combinations
Disclaimer:
These tweaks may only help certain hardware / software combinations, the result for me was improved fallout 1 stability and a reduced number of blackouts. Both of these settings give only a very small performance boost (~= 1%) and can have nasty system stability side effects so there is really not much reason to leave them on.
Also, check http://www.nma-fallout.com/forum/viewtopic.php?t=39638 thread out on No Mutants Allowed about how DxWindow can solve blackouts.
