the talk here is not about how small everytning looks, thus res patch sux. it's about game slowdowns while using it. please keep on topic...
so, anyone discovered a way to get rid of slowness when playing with res patch? i have the same problem...

Are you sure you turned off vertical sync ? Because that alone doubled my fps. Another way to further reduce slow downs apparently is to rename the ddraw.dll file in your fallout folder. I'm not entirely sure it works and it may affect your game in some other way (to be honest i have no idea what this file is for) but I tried it and so far it seems to be working. Now my game runs extremely smoothly.

This is the solution :) The DDraw.dll must be some relic of the ancient directx times. FYI I think it manages the way the API (DirectDraw) will work with the game.
Renaming it or deleting it will force the game to get the newer one which is located elsewhere (probably windows/system32).
Solved! And even solves the High Resolution Patch slowness!

Many-many thanks! problem solved!

Yes ! Thank you. Plays perfectly now. :)
This should be added in the MODs sticky thread along with the Resolution Patch.

that did the trick for me, too! i agree with the others that this info should be stickied along with the list of mods.

This worked perfectly for me. Thanks! :D

Thanks for the fix! :)

Awesome catch! +1 to you! I was wondering if the problem was with my laptop. After renaming the file everything sped up 10 fold. Thanks again.

The game was displaying weirdly on my screen... flickering. It was unplayable. Then I tried that Resolution Mod and it works just fine :)
I also renamed that DDdraw file and set the resolution to 800x600. The game plays fine now :)
Thanks to whoever posted about this mod and what to do to improve it! :)

Many thanks for the solution! (ddraw rename)
But I got another problem from this, I get pixels going missing because of this. Missing as in they are off coloured like a negative (shows up alot in the startup, but mostly disappears in running the game). I'm running vista with an Intel GMA900 graphics. Maybe the implementation of DX7/8 is crap on the Intel. Anyone got the same issues?

Err, you might want to get a graphics card, and not an onboard if you are going to play games. Try updating your drivers and DX?

I'm having trouble locating the hi-res patch online. The only result I get is the "No Mutants Allowed" website forum that gives a link to the download but it is a bad link. Any thoughts on where I can download the patch?

Now that's a helpful user, thanks man!
GoG Team - please fix it and release updated version.

I believe this is it:
