fps running slow?


Recommended Posts

it is amazing how one forgets things , recently i have been getting quite low fps readings  flying out of Perpignan and I had put it down to the new airbus 318/9  which on the ground gave 32 fps all the way to about 4 thousand feet where it started to tail off down to about 12fps . here it would stay only to recover a bit at altitude.

I finally twigged what we all knew when we first started playing with fsx but forgot,    i had the sea at low2x,   by lowering it one notch to 1x i recovered my fps to 65fps in one fell swoop. yes the sea doesnt look as nice, but does that matter at 35k feet?

and yes when i climbed out of perpignan i passed 4k feet as i got closer to the sea, so easy to fix !

Lowering that same setting was what made it possible for me to finally get that last ATWC5 PIREP video done... strange really that it should have such an impact over London, especially considering I was going away from the sea to begin with in that flight!

I have always struggled with low fps as my machine is not that powerful however having played some other games for a month or two and started up fsx the fps has increased so much more than before. Can't see the reason why.....

Increasing water effects does have quite a hit on frame rates, but the amount of degradation does seem very affected by the model of graphic card in use. This may be a subjective observation, but do feel that Invidia cards handle the effect better than AMD cards.

 

Other effects which can drastically affect frame-rates are 'Lens flare', 'Light bloom' & 'Ground scenery shadows' when enabled in display settings.

 

The ground scenery shadows causing such a frame rate hit is a bit of a mystery with todays hardware - back in the mid-1980's with 8-bit Atari computers I used to program graphics using 'sprites' (remember them?), very blocky, 2-D graphics by today's standards, but visually could be much improved by adding ground shadows which was very easy to program, but did put in a bit of a 'wow' factor. This had almost no effect on frame-rates.
