For Strife, you could try
zdoom. It is a souceport. In practice, this means that the game will run much better, in performance but also with mouselook, widescreen, etc...
You need the WADs or whatever (I have not it installed right now, but if you
really can't figure it out, I shall help with a step by step explanation.
Keep in mind that the sourceport is not a remake, so you need the original game. You can buy it on ebay or similar, but it is easily found in sites like abandonia or the pirate bay.
If you are interested about these kind of games, the sourceport can run hexen, heretic and doom (obviously :P) too.
EDIT: I forgot how easy it was. Just extract the zDoom.zip file to a folder and copy inside the game (just the STRIFE1.WAD) and you can play
