Low FPS on Ubuntu 16.04 64Bit (with a GTX760)

[KarnageRage]

The title descripes it mostly...

my relevant specs are:

CPU - Intel i5 2320
Mainboard - Asus P8H77-V
GPU - Zotac Nvidia GTX 760 (4gb version)
OS - Ubuntu 16.10 64Bit

I can get the 60 frames, when there isn't very much to load on the screen. The worst drops are, when I'm at the edge of the map and take a look on the whole map. Any idea how I can fix this or how I can improve the GPU-Performance under Ubuntu 16.04 (especially about handling a huge amount of data in this case)?

this is why i use dualboot :(
linux never developed their game platform fps problem

1) make sure your graphics driver is not limiting fps to the sync rate ("sync to vblank"). you can enable/disable this in nvidia-settings or via commandline.
2) try lowering overall graphics settings. disable antialiasing, lower shadow quality, etc. run at a lower resolution.

I also upgraded Ubuntu to the 16.10 release, so I got the kernel-update from 4.4 to 4.8 and since this I already got some more frames, but not enough.

Okay in the GUI settings window of NVidia I almost skipped the option to disable it. So my frames where limited.

thanks for the help @Don.Gonzote

I use a pair of GTX760's & run without limits on framerate (sync to vblank) using the newest nVidia beta driver 375.10 (manual inatall from nVidia-- http://www.nvidia.com/Download/Find.aspx?lang=en-us). Am getting a solid 60 FPS & depending on textures can go up to 90 FPS. And yes--I'm SLI--with the right settings SLI works very well in Linux. Running Debian Sid/Unstable. I can send my xorg.conf to you if you want (Don't trust Ubuntu or ANY other distro to auto-config the setting for you!)

[KarnageRage]

sorry... but I only have ONE GTX 760...
did you only got SLI running or did you also made other configurations to improve the performance?

single 960 here, arch linux. i wouldn't mind taking a look at your xorg.conf if you can pastebin it.

Yes--SLI running in Debian--works VERY well--Using AFR (alternating frames).. I'll paste all of it here..

I'm not a fan of distro-config---as you can see, I had nVidia xconfig done & then I modified where it was needed....DO set the coolbits so you can "really" do card mods..Ignoge the "AFR" setting SLI only & I use the nVidia utility for auto display setting (modes nvidia-auto-select).

In the hanger I get 40~60 FPS & in open space I get 60~90FPS--all battle modes also 60~90...Both cards run about 45C under load (remember to remove the stock heatsink & apply BETTER material--I use Artic Silver 5 & my cards went 5C cooler) Using the EVGA dual fan 760's.

Totally forgot something---Check you Nvidia-Settings for your card & see if the card is running "gen-2" or "gen-3"----if your motherboard is "newer" (3~4 years old) you "should" be running gen-3. To get there (8GT's instead of 5 GT's), create a config file in /etc/modprobe.d (debian-based distros--check for other distros) called nvidia.conf & just put:

options nvidia NVreg_EnablePCIeGen3=1

in it --save & reboot-then check if you have 8GT's for your video pipeline......

[debianmainuser]

Just for grins I shut off SLI & ran my main card only......In the hanger I am getting 60~90FPS & in open space about the same....not sure why I'm getting better framerates in hanger & about the same in Open Space----but You should be able to get close to that with your setup---Don't buy that "it always works better in Windows"--current video drivers are very close to the same & sometimes better in Linux these days.....You just need to look at the relevant forums (nVidia dev, Ubuntu & that kind). Take a look at www.phoronix.com/ for current info.

[KarnageRage]

okay I'm kinda lazy.
Do you have some guides you can share with me/us where the topic is about some "essentials" to improve the performance? I would appreciate that, if you can do this. But I'm already really thankful for all the tweaks you posted here.

Unfortuantely your post about PCI gen-2 or gen-3 wasn't that helpful for a newbie ... sorry. I checked the ♥♥♥♥♥♥♥♥ Asus website and my MB has PCIe Gen3 (and I have connected my card into the right slot). It would be useful if you can give the instructions (or C&P-command) to check if gen2 or gen3 is configurated.

[debianmainuser]

OK--I'll be a little easier on you :)
1. Open a text editor & paste the info I have above into it (The text bit that starts with "options") 2. Save the file as: nvidia.conf
3. Open a terminal window & type: sudo nautilus You will be asked for your password--do so.
4. A File Manager window will open--Navigate to /etc/modprobe.d & open that folder
5. Take the nvidia.conf file & put it into the modprobe.d folder---you most likely will see other folders/files in that folder.

Verify that all the steps above look right & then reboot.
When you get to desktop again, recheck your nvidia settings panel...where you see all the "specs" it should say "Gen3" instead of "Gen2" for PCIe Generation & the Maximum PCIe Link Speed should say 8.0 GT/s instead of 5.0 GT/s

This is the "easiest" mod you can do to "speed" up your card----You have increased the "pipeline" for video transfer. Everything will be slightly faster afterwards--movie playback to gaming.

Here is the reference info for the mod: http://devtalk.nvidia.com/default/topic/545186/enabling-pcie-3-0-with-nvreg_enablepciegen3-on-titan/?offset=2

[debianmainuser]

As far as doing xorg.conf settings/changing.......If you are not confortable creating/editing main system files (where you might get dumped into commandline if you make a typo), I would just stay with the mod I referenced above & make sure you disable the sync to vblank setting...when you do the setting change, make sure to goto nvidia-settings Configuration & "Save Current Configuration" Accept the default location for the saved file....that way vblank won't bother you again.
