That agrees with your above comments. i'd be a little careful about using a CPU monitor and the "fact" that the CPU is 100% as a measurment of the CPU being the bottle neck. while i haven't validated this comment, my experience has shown that most "frame rate" 3D applications will use 100% of the CPU, depending on their design, where it is clear that the CPU is NOT the bottle neck. i think this is just a function of the fact that most 3d games/simulations are basically big state machines, trying to run their propogate/render loops as quickly as possible, and are not intended or designed to yield their runnable state on purpose. until recently, i was running an AMD 2800+ with 512MB and a Radeon 9800 Pro. this combo performed quite reasonably for both FlightGear and X-Plane, on Linux and Windows ... using a Radeon 9800 Pro. by current standards, a 9800 Pro is a pretty aged card, and a 5200 is _ancient_. what _i_ usually do, when trying to work though "what video card to get", is to go look at cards that came out sometime _before_ (if i am looking for price then performance) or _after_ the CPU (if i am looking for performance then price) i have hit the market, maybe up to a year or so in either direction. my thinking on this has been that if you look at the CPU/GPU cycle over that last 10 years, the GPU sweetspot for a given CPU is around the time frame that the CPU hits the market (as logic would dictate), give or take a year or so. so ... if the CPU and GPU "era" match, they probably will work well together. and of course, if you can find old reviews from the time, even better ... > To that, I will ask for good and bad stories about 64 bit > machine running SuSE 10.1 or the likes.

SuSE has GCC 4.1.0 and the 64 bit lib64 i don't know if FlightGear is 64 bit clean ? that would be issue #1. i recently built my NEW AMD-64 x2, and am using Kubuntu. when i was doing my research, deciding if i should go with the 64 bit OS, it seemed to be pretty clear to me from my research, and from others posting to various boards askings the 64 bit question, that 64 bit is really still kind of a pain for "user" desktop machines. finding software is more of a hassle, and trying to do 32 bit/64 bit libraries and layers is a hassle. and many people seemed to make the same comment, that generally, they didn't feel like there was much sense of a big gain for the trouble ... fwiw. > -- > 73 de Donn Washburn Tony -- X-SA user ? 0.5.1 is out !
