Fluctuating FPS: 40-60 and choppy/laggy on high end machine [FIXED]

[delatroy]

Just to add to this, I also have a GTX670, i7 980x and with AA, TA set at 16, vsync off, I'm getting between 35 and 65 FPS in outdoor, complex areas. I tried quite a few commands to see if any had a decent effect but nothing moved it higher more than around 5fps.

 

Some changes:

seta com_videoRam "2048"
seta image_useCache "1"
seta image_cacheMegs "512"
seta image_cacheMinK "3072"
seta com_machineSpec "3"

 

There are some D3 commands which get removed by TDM like r_displayRefresh [Hz] which is used to set the monitor refresh rate - not sure why.

I got the same yesterday when playing. I was in a sewer area and, my FPS (using FRAPS) kept fluctuating between 43 and 32. I turned my AA off, and the fluctuations went away after a minute of gameplay.

GForce GTX 460 - latest drivers, updated to play BF4 BETA (which was not impressive)

I am not looking at the svn log or code, but I remember that a number of these were not actually used in the code, since the framerate is tied to the tick rate in normal play (which is a whole mess of its own). So they were removed to reduce confusion.

I cant see any posts where I found the fix for the issue, so at an educated guess I had a corrupt driver install. Uninstalling and then doing a driver clean and reinstalling has most lickely fixed it.
