Yeah there is not much difference. I know what PopeJo ans sXe mean. There is only a coulple of differences I notice..
1) I much prefer the Q3 sounds. They are more snappy such as when you hit someone. You don't get that nice crunching sound when they explode. The rail hum is also very soft and smooth. I compared them both and the ability to locate players on Q3 is much more distinctive. The opponent weapon is much louder and clearer as they approach. On OA your own weapon seems too loud or bassy.
Out of all the weapons I think OA are all better except the saw thing and the lazer shooter.
2) The models are very high textures and so are some other things which don't change when I lower settings. On my own Windows machine Q3 performs much better that OA. This maybe a stupid question but does Q3 use Direct3D and OA uses OpenGL? I have not looked at any of these settings in my display options. On one defrag map I had the lowest quality settings yet could not make this jump at a waterfall thing at the start of a CPM map. I switched to Q3 and don't think I missed it once.
I love OA and Q3, they *do* feel the same. I've even had people play it not knowing what it is and they all say "hey this is q3".
95% of people I play with on q3 won't have heard or know what OA is. I get the urge to play both. Me and moo will be playing on q3 and one of us will always say "OA time?" and switch. As 1.16 players we play the same maps every day, mainly the same 3. You get to know them and can move around fast. The corridors and narrow and there are rarely any parts when you can get shot in the back. I used to think this was a bad thing but now I see why it's like that. You are alway close to an area where you can defend yourself.
I would like to find some nice maps especially for TDM and 1v1. Anyone have any recomendations?
