Could be heat related. use a monitoring tool like HWMonitor to see if the CPU or GPU are going over 60. Heat can cause the laptop to throttle itself to a lower speed.

No new GPU drivers? has anything changed since you had 45fps?

Try a lower FSAA, perhaps even turn it off. It murders FPS.

Also, with the fix to SMAA(Dev-branch) its now a decent alternative to FXAA.

Heat isn't the problem (system started after hours and the issue is present immediately, heat is about 35 degrees celsius/95 degrees fahrenheit).

Graphics Driver Nvidia: 320.49 (latest)

And yes - to play with the options FSAA, ATOC and PPAA changes the situation. To turn off FSAA, ATOC and FXAA/SMAA moves the fps from terrible 11 (FSAA 4x) to bad 28. And there is no performance-recognizable difference between FXAA ultra and SMAA standard - ultra. Turning on FXAA ultra takes 4 fps.

Altogether it's no compare to the situation before. Some days ago 45 fps and a nice looking world - and now 28 fps and a picture like from Commodore Amiga 500... this really sucks...

If it's not heat related here's a few other ideas:

    Lower the view distance if its above 2000.

    defragment your hard drive.

    add -nologs to your startup parameters.

    check to see if 'iehighutil.exe' is running, its a bitcoin mining malware package that uses your GPU.

    Run a full malwarebytes scan.

RE: FXAA vs SMAA. I found that SMAA would use about 4% less GPU than FXAA, every little helps in my opinion.

Great thanks for your help, Chomp, but nothing of that really worked.

• lowering the view distance from 3000 to 2000 didn't change anything
• my hard drive is constantly defragmented
• "-nologs" took no recognizable change
• "iehighutil.exe" is not existent on my system, malewarebyte-scans are running repeatedly

• FXAA vs SMAA: i can't see any performance improvement, but on FXAA the textures are much more sharper and looking much more better

It must be an issue in the new patch. Before the last patch in my sight everything ran smooth and well with good video quality on my i7/GT 650M. And as i understood - there wasn't any new and big graphic-feature released or anything like that...

But, thanks again.

Really sorry nothing I suggested helped you out.

I guess you could try deleting the game from steam and reinstalling it.

Also, with it being a laptop you could try forcing a few startup parameters, maybe the game isn't detecting your i7. Try adding these:

    -nosplash -skipintro -maxmem=2047 -exThreads=7 -cpuCount=4

try cpucount=4 first, then try cpucount=8.

**edit: You're 100% sure the game is using your 650 and not your onboard graphics(Intel HD Graphics 4000)? long shot but it might have defaulted to the wrong gpu.

Damn... i guess you could be right with your long shot...

I can't see any activity on my GPU. It seems, that the game doesn't start the graphics adapter and runs on the onboard Intel HD 4000 since the last patch. In the option-center i can get a list, which program has to use the Nvidia GPU. But the GPU ist already chosen for Arma3.exe.

Don't know what to do now...

Interesting, perhaps you can disable the intel graphics from the bios?

So... deactivated Intel HD 4000 and GT 650M... restart... activated onboard and Nvidia and - it works.

But altogether the patch costs me still about 10 fps to the status before (v0.72.xxx).

Thx for your helping ideas, Chomp - but there must be something unedible in the last patch for my system.

@Bohemia: I try to change the subject of this thread.

Mass closing ancient tickets with no activity for > 12 months; assume fixed or too trivial.

If this issue is still relevant in current dev build, please re-post.
