Dennis,I am also using the 175.16 drivers for XP with no Nhancer anymore. Some people are haveing great results and others are not.

I generated my understandings directly from the MS posts quoted. I find that the most technical explanations tend to dilute understandings of real world effects. For instance, " . . . then we will send 40/30 or 4/3 as much textures per frame." Here it is in sim user-ease: Moving the TBM number above (or below) the default 40 Can help decrease the forward flight stutters. The take-away is that if stutters are occurring at a sustained 25 FPS, some frames are not unique and are simply being repeated. Playing with the TBM number helps fill the (stutter gaps) with unique frames . . . and the rest. "Where n is the amount of bytes we will allocate for one pool of vertex and index buffers to store geometry." Oh yea, I get that?!?!A buffer is an amount of memory that is set aside for some later or supplementary use. A pool is a pool of it. Bufferpool is a pool of memory (Vram in this case) that is set aside to provide quick (er) access for some need. In this case, panning views. It could also help "feed" the TBM process(?).

Yes some people (not FS people) are saying that the 175.19 driver got pulled and was causing frame rate problems. ??RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT
