SUBSIM Radio Room Forums - Help needed : offer an U-boat game.

I have tried Sub Command and Enigma (just got it today, so it's strange, no manual ship locating, strict time for training, and still impossible to mine a sub with surface ship) I have SH3 but my laptop has an integrated video card (intel extreme graphics 2 64mb) and it doesn't supports pixel shader. Can you offer more games U-boat witch would be interesting and wouldn't require a very good graphic card? I enjoyed SC, but still don't have a good minds about E:RT. Laptop : 1.4 Ghz Pentium M Dothian (1MB catche) 512 SDR RAM 64MB video as I said (doesn't supports TnL, pixel shaders and new stuff *cry*, i still enjoy it since i can play world of warcraft with it.)
