ListPlot3D[] - rather slow?

I have kind of finite difference solver, typically used over mesh of 250x250 size, producing scalar values for each mesh point (also - typically values produced are rather smooth). So I'm trying to visualize results using ListPlot3D[], basically passing only the resulting 2D list of results as ListPlot3D[] argument. However, the resulting visualization is very slow to build, and interact with (am using Mathematica 7.0.0 on Linux, on a 2.4 GHz Core 2 Duo machine, with NVIDIA Quadro FX 770M graphics) - each redraw takes couples second, and soon after Mathematica just start eating my swap memory and brings the whole system very slow. Now, I have some experience with using OpenGL and that kind of stuff, and I know several tens of thousands of polygons is not something particularly problematic for above graphics hardware. So - I'm wondering why ListPlot3D[] is so slow, and are there any options of this function that could be used to make the resulting visualization more responsive (so far, I've only tried setting PerformanceGoal option of this function to "Speed", but then resulting visualization looks like crap, and also I've tried to set PlotStyle option to "None" and this kind of works, but still it would be much more helpful to be able to see actual surface generated, instead of lines mesh... Also - is there any other method that could be recommended for this type of visualization (I guess lots of people are doing same kind of work, and would be interested in alike kind of visualization)? Thanks.
