Declining FPS on core i7

I tried that with multiple patches. Makes no difference what's or ever. I'll keep it on.

Now on top of all the mess and low performance, i get a crash every second offline mission. I didn't even bother going online.

My FPS seem about the same with this patch (on average) but it does seem smoother to me overall. I don't get many of the 100FPS to 1 FPS drops anymore which is a big improvement.

It is smooth yes, but look at my last post with screenshot in Bug thread. Shows the step backwards regarding trees. So annoyingly seen "feature" while playing even I usually do not look at vegetation while flying except for navigational purposes.

Same FPS drop happen to me.

Vsynk may be a problem. It cuts FPS from 60 to 30 to 15. Need to use a 3rd party utility to enable triple buffering if vsync is badly needed (drivers CP handles triple buffering in OGL only). In release version there was no true fullscreen and vsync could cause less problems.

Patches cause slow downs because:
- files get more and more fragmented when patching as HDD gets filled in month by month and internal Steam defrag is not good enough.
- new versions may not woork well with old conf.ini and other ini files. Need to delete Documents/1C-Softclub folder (backup control and info-window settings first)
- new patch files need to be cached by windows again and this takes time
- if you did not add both Steam and Documents/1C folders to 2-3 exclusion lists of your antivirus (real-time file monitor, network monitor, etc.) , it will scan new patch files when loading them
- new graphics drivers introduce new image enhancements (like new AA methods) which may be switched on by default in drivers.
- AA was improved in game a bit and may conflict with drivers AA settings if used (need to be set to application controlled).
- etc., etc. Please see a link #2 in my sig for more ideas of what can go wrong in a system.

Try running in pseudo mode, disable all background applications like TS overlay or Skype, upgrade motherboard drivers, check if PSU is clean and not getting overheated, check out if GPU fan is clean of dust, check if clocks and temps are the same as some months ago, etc.

I have never come across this in all my years of gaming and multiple Ati gfx cards – is this something peculiar to nVidia? Using VSYNC in every game I have limits the upper frame rate to the screen’s refresh rate, but does absolutely nothing to lower frame rates. I have always used it to limit frame rates this way and avoid ‘tearing’, and still do. It works this way for me in CloD currently.

The way vsync functions causes the loss in framerate (triple buffering is a nice technique to help solve some of the issues). However this loss in framerate only occurs when your framerate drops below your refresh rate. nVidia recently has released their own iteration called 'adaptive v-sync' that aims to correct the issue with vsync cutting framerates down when under your refresh rate, and to not have input delay when at/over your refresh rate.

For a nice explanation of how v-sync actually works and why there is a performance decrease I would recommend to take a look at this nice little blurb from the Hardocp forums,

I hope this sheds some light on the mysteries of v-sync

I don't think/hope that the Lod problem was intentional I only started seeing the Los circle after I was flying in England in France it was normal... hopefully they release a quickfix for the Lod and hurri this week.

I just did a complete re-install and copied back in my key bindings only and I clawed back some of the lost fps. Now a steady 45 FPS with all graphics full.

But nothing like the 80-140 I uesd to get.
