I have just upgraded from a Geforce4 MX 440 to a Geforce4 TI 4600 and I cannot see any noticeable difference in graphics quality or frame rates.
There have been a lot of comments re - frame rates. Some are getting good fps and others not so good but there are no set bench tests for use with FS2K2 in order to make an accurate comparison with others.
Most simmers have purchased add-on sceneries, sliders are set at various settings depending on cpu power. There is no standard for comparison.
I used to use FSBench (FS2000) to compare my system with others and was able see at a glance where inprovements might be made with regards to hardware and if any improvement was worth the expediture.
We know that FS2K2 is cpu dependant and I work on a ratio factor to estimate improvements in fps.
If you increase your cpu capacity by 10% say 2GHz to 2.2GHz at some considerable cost, as a guide, the fps might increase by 10%.
If you were getting 10 fps you might get an increase of 1 fps.
Can there be something set up for FS2K2
Here is the link to fsbench for FS2000.
