Hi to All...i have a problem...i can't play Skyrim with any mods installed, because after some secs of apparently good gameplay the game start to lag a lot and when i walk i see a lot of lag.

My Computer's Specs are : Intel Core I7 3840 M ( I overclocked it at 4,0 ghz but even like this nothing changed), 12 gb ram, 2 ATI 7970 M Crossifre (the drivers are updated).My Hard Disk is not empty.

I did 3 things to solve this situation :

1)I even set all the details to Low....nothing changed.I removed big mods like falskaar etc.

2) I removed all my graphical mods, i dont use enb,

3) i removed the rest of the mods See that Skyrim is QUITE good (the game speed is decent but i see is at the limit , like if i add one more thnig and it will become slow again) just when i disabel ALL my mods (i have near 50 medium mods installed).

What can i do?

Thanks for your Answers.

One possible reason would be: To note about dual-GPU cards (SLI or Crossfire) is that the VRAM does not add up. If a Crossife configuration say it has 2GB of memory, it actually has only 1GB per GPU. The same textures, are loaded up on each of the 1GB of VRAM for each GPU to access separately.

Meaning, you obviously reached the maximun amount of VRAM that every GPU is using.

Skyrim behaves strange on a Dual GPU, and weird enough if your VRAM goes to the limit.

I don't know what mods you are using. Big texture mods going right away yo your VRAM.

One problem could be your GPU can't flush fast enough your datas from your VRAM to the main system RAM, therefore the stutter. !!!!

Normally you shouldn't have problems on games that can make use of dual cards - Crossife configurations.

------------------

It seems that RadeonPro lets you disable Crossfire on Dual-GPU cards. (or see here: http://gotnorice.no-ip.org/crossfireprofile1.jpg)

I don't know if it's applicable on newer Dual GPU's . !!!!

Hi, thanks for your Answer, i disabled crossifre and enabled the non-graphic mods...still nothing the game lags a lot....Is there a working Crossfire fix? Or i can't simply do nothing about it?

Well, i assume you have loaded your mods via NMM or similar mod manager.

So, disable all your mods and start a new character. Keep, your AA and AF settings "application controlled" on your CCC panel. and change them accordingly on your Skyrim -> Options menu.

You have obviously the i7-3840QM (over. at 4.0 GHz) (and not 3840M)

Delete your skyrim.ini and skyrimPrefs.ini files. ( C:\Users \ [ Your name ] \ Documents \ My Games \ skyrim )

Try to play at 1920x1080 with 8x AA and 16x AF. (settings ultra) - Vsync: Enabled

Your frame rate should be near 60 fps.

Try that, and report what happens. (play that way for 1 hour for example)

-------------------

Disable any Antivirus, or any background program(s), that's running and can interfere with the Game.

-------------------

Τo be honest. you shouldn't have problems to play at high, any game you throw on this Laptop.

Ok.Tomorrow i will try! Yes i load my mods with nexus mod manager and i have the 3840 qm...i will do as you said but i can't run for long the game at 4.0..i will use the default clock speed.

I will let you know here what will happen.

Actually your CPU works with turbo boost at 3.8 GHz. There is nothing much to gain, so the best it to take it back at stock speed. (2.8GHz)

Except that, you stress your laptop too much - and as i said earlier, that's a very fast laptop as it is anyway. !!!

See you tomorrow then...
