Hi guys,

Last night I upgraded my old MSI GT780R with Nvidia GTX 670M 3GB graphic card. Original gpu in laptop was GTX 560M. I installed latest bios and latest driver for GTX 670M, but for some reason 3D performance in games has actually dropped.

For example, on old gpu (560M) I could play BF4 on medium setting and get really nice framerates on lower resolution, and with the 670M even on lowest settings and resolution BF4 is unplayable.

I was also testing gpu on some other games, and performance is awful. Games I could play on high settings with 60fps (Valkyria Chronicles, Dead Space 2 and 3..) are not even close to 60fps with the new gpu..

I'm sure I'm missing something, any help is much appreciated!

Thx

download newest driver for 670m i guesss its 391.35

Download ddu , display driver uninstaller. Put both of these to desktop. then
1. boot into safe mode and run DDU, choose clean and restart (recommended) and remmeber to select nvidia from side.
2. after it completes it will boot itself automatically. Start normal windows and press your newly downloaded drivers from desktop and do "clean install", when you update drivers it will ask for custom or advanced install, something like that press it and then put x mark to clean install.

Temps are ok, 60-70 both gpu and cpu under heavy load, I used mx-2 thermal paste..
No idea about vbios, to be honest I don't even know what's vbios.. How can I check that so I can post it here? thx

You said "I installed latest bios and latest driver for GTX 670M"
I thought you mean Updating vbios only but you meant newest bios for your laptop? This means you flashed probably vbios of your old card into this one :D

You need this one if yu already didnt flash vbios : https://www.techpowerup.com/vgabios/123960/msi-gtx670m-3072-120116

Look your GPU memory chips closely, do you see its samsung and hynix memory, if there is another model chips then this is not right file, check this link https://linustechtips.com/main/topic/764343-ddr3-and-gddr5/ and picture where vram shows in red,, these are the chips you need to check

Before all this download gpu-z and post picture of it so we can see your vbios version. Secondly you can backup your current vbios with GPU-Z look google how. Put this file to desktop and usb stick for backup.

Here is a video how to flash vbios, i take no responsability if you fail it somehow: https://www.youtube.com/watch?v=ehmhWeBLgk0

Disable antivirus and firewall before flashing, also all malwarebytes etc antivirus programs.

Thx mate, I'm on my way home, will check that in an hour! But I really want to avoid flashing vbios 'cos I heard it's risky and I really don't want to brick my laptop..

Here it is:

when I click on lookup, it opens the same link you posted above.

edit:I looked at my gpu, I can see only hynix memory, can't see any samsung chips

Here's the picture:

I backed up my vbios with cpu-z on usb stick, tried flashing gtx670m vbios but every time I tried nvflash did not flash it, instead gave me list of commands. I tried 3 different versions of nvflash and it was the same every time.

Any suggestions? Thx

Just this morning I realized that it looks like I already have gtx670m vbios, that's what I get when I type bios version (from my cpu-z info) into google..

I really don't understand :(

Go to nvidia control panel and 3d settings there select "power management option" and set it to performance only. You can also go to your exact game from this screen and select the same thing if you want to test 1 game first before setting this to everything at once
