Will the performance be much better than in the original BF 2142? I actually think that the performance at this moment is terrible and not acceptable for me. I hope so.
We are using the polycounts and texture resolutions as per bf2142/bf2 so I think I'll be safe in saying that the performance should be around the same. However, we are trying to optimize as much as possible to get it running as best we can on even the minimal specs. I hope in the end everything will run smooth enough for you.
Loading times: keep the archives small. And thanks for a low polycount, my old fx5200 doesnt like titans sometimes. Most of the time. Pretty much always.
