I honestly feel ashamed that I didn't know this site for so long. Maybe because whenever I typed 'Unreal' instead UT greeted me. Several interesting things going on here, I can see! I can smell!
Several questions

1. Whenever I move the mouse cursor slightly in the game, it moves too much so I cannot aim accurately (not in the menu screen, only seems to happen in the game). I cannot believe I loved this game so much that I lived with it for so long but felt that it was time to fix it.
Searched the net and people recommended me to use OpenGL but unfortunately I'm using laptop and the option does not even exist (I'm using GOG Gold version 226). What should I do

2. I don't know if this is appropriate or not, but this is relevant to the first question. Since OpenGL seems not supported with my laptop, I ended up myself with direct3D 10 renderer for Unreal! (kentie.net: wanted to link it but I cannot now since I'm new here...) Even though I found 227 fan patch here, since I won't playing the online due to my rather hefty internet condition for some reason unfortunately, I was thinking of giving it a shot.
The problem was that, at first only the sound seems to work but the screen wouldn't show up for the menu. I pressed ctrl+esc and an error message saying 'SetRes: D3D::Resize failed' pops up. The error log is like this:

I also sent this to the author of the mod, but just wondering if anyone who played this game for a long time could help me a bit of this situation (at least the source of the problem).
3. I see some delicious looking maps in the Wiki! Do I just have to download those files into Unreal Gold\Maps and play? Any other things required or so? I love team matches. So much fun.
4. Lastly, is there any way to assign a seperate key for dodging? It's quite annoying since I sometimes dodge when I didn't intend to with the original key assignment.
Thanks!
