GTX 1080 worse than GTX960

Recommended Posts

I just updated my video card from a GTX 960 to a MSI GTX 1080. I did this hoping to improve performance is high density ares like LAX and SFO. I am actually getter more stutters and less FPS than I did with the GTX 960 at the same graphic settings.  

Any advice would be appreciated.

Did you use DDU to facilitate the card change?  It makes upgrading video cards and drivers simple... it will uninstall your 960, delete the drivers, and clean the registry of all relevant nVidia video card drivers.  And then shut down the computer so you can change cards.

Once the 1080 is installed the new card's manufacturer's drivers should be installed before upgrading to drivers of your choice.

Make sure you delete the shaders in P3D after installing the new card.  It's a step a lot of folks forget.

Also, make sure you have the additional PSU power pigtail(s) to the GPU card edge connected properly.  It's possible the 960 doesn't use those additional power connectors--the 1080 requires them to be connected (and if using a multiple-rail PSU, each of the two pigtails should come from a different 12v rail).

Big mention here... when you come to install the driver, make sure you choose custom install and untick everything except the driver. You don't want any of that extra bloat nonsense to be installed :wink:

I upped from a GTX 980 to GTX 1080, after going from P3dv3 to P3dv4.

I have FSDT KLAX and Orbx San Diego and Palm Springs in Orbx South California. (As well as Orbx over the planet)

I see absolutely no change in smoothness or FPS from the 980 in 32 bit to 1080 in 64 bit. This area (KLAX) appears to be a stutter fest, even with all sliders left most, it makes no difference.

When upping cards, always use NVidia custom install and wipe the shader folder. The 1080 is much faster on paper and has twice the VRAM. Certainly helps with the fancy 64 bit lighting effects but doesn't add smoothness or FPS!

I believe a top GPU will never cure the stutters in the aforementioned areas. P3d and FSX before, is a CPU intensive program and has issues with certain areas. It's the CPU, the RAM memory speed and the SSD speed (ideally PCIE at 3200 MHz or higher) that will be of greater benefit for smooth rendition of flight.

Just my two penneth.

Best regards.

I did not delete the shaders. I will try that. I have a Corsair modular 850W PSU. I did connect both the 6 pin and 8 pin power points.

Thanks,

Unfortunately, I did the express install. Maybe I should uninstall and start over. 

Thanks for your response Howard.

I don't like all the extra stuff either, but the express install won't affect your frame rates.

Hello

As the rest have suggested,  After updating your Graphics driver or changing your Graphics card Delete the Shaders folder and the Prepar3D.cfg file and let Prepar3D generate these again when launched next.

This will not effect your Add On's,  You will just need to adjust your graphic \ scenery settings again to your prefrence via Prepar3D > Options when you delete the Prepar3D.cfg file.  The Shaders will take a minute or two to generate again. 

Copy the 2 set's of Tex below and Paste them into your windows search bar, One by One and click on the result,  this will bring you directly to the correct locations

Right click and Delete the Prepar3D.cfg file

%APPDATA%\Lockheed Martin\Prepar3D v4

 

Right click and Delete the Shaders folder 

%LOCALAPPDATA%\Lockheed Martin\Prepar3D v4

 


 

Also for best results when Installing your new graphics driver click Custom Installation and Tick the box for "Perform a clean Installation". 

As mentioned above you can also use a driver cleaning utility like DDU Driver Display Uninstaller to complete a clean uninstall of your old driver and then proceed to reinstall \ update your driver

Elaine nailed it (that's officially a habit with you Elaine!!!).  I'd forgotten that the new NVIDIA driver package has the Clean Install option - means that you don't have to mess with wiping the drivers before installing the new ones (CAVEAT: If your drivers are a year old you may wish to Wipe them anyway).

Anyway, Greg I think with the terrific advice you've received in this thread your system will be running GREAT!

Best wishes my friend.

I'm glad this was posted. I just got my GTX1070 TI today and will install it tomorrow. I'm sure I would have forgotten to delete my shader folder. Thanks.

Express install is a recipe for problems.

If stutters appear with this lot, we need a new flight sim coded!!

Thank you all for your replies. I will re-install my GTX 1080 either this afternoon or tomorrow and report back. David that would be quite a system!

I took your suggestions. Uninstalled the old drivers using DDU in safe mode. Did a clean re-install of the new drivers. Then I deleted the shaders and the P3DV4.2 cfg. It made a significant improvement. However I am still getting more stutters than I did with the GTX 960 in high density areas. 

Thanks everybody for all your help!

If you read the P3D and FSX forums long enough, you might come across the concept that to get the most out of your system your settings need to be balanced with your hardware. It is a trial and error process. Once you have that sweet spot, just dropping in a better GPU or CPU will NOT guarantee you better overall results.

I've seen many people install a new card and immediately crank up the settings - many times getting worse results. Once you have the new card installer and a clean driver install you may still have to fine tune your system to keep in in balance.

Adjust your settings - some may need to go up and some may need to go down.Many times INCREASING a specific setting will result in better performance - too many people just think of decreasing settings to improve. Not always the case.

Greg,

I didn't see what Windows version you were using, but, if it is 10, it could be this issue:

 

Stuttering due to WIN 10?

Six months on, and let's check in on those 'stuttering' Windows 10 PCs. Yep, still stuttering
Gamers say performance woes haven't been addressed as Spring Creators Update looms. . .

Thanks Vic!

I had a very balanced system with my I7 4770K and the GTX 960. I have noticed with GTX 1080 that 4096 textures is soother than 1028 textures. I will keep trying to save my investment but I can always go back to the 960. I was really after the 8 gbs of VRAM for the new P3DV4 airports that are releasing. It maybe that the 1080 gets put away until I upgrade the CPU, motherboard and memory.

So far I have not seen anything that will solve the OP's issue and he has not stated anything worked.  His GPU upgrade was modest.  If there is any earth-shattering fix, I will pin it.  Everything suggested is well-known especially deleting the shaders folder (see AVSIM CTD Guide, page 24).  I think deleting the shaders folder and rebuilding the P3D.cfg are the two best suggestions posted so far.  Even with my i7 7700K and GTX 1080TI and my two M.2 drives, I see a whole lot of stuttering in the LAX area with modest settings and I have not found a solution yet.
