FPS locked at 15

[mraymond]

Everything was running fine, until a few days ago I started the game and found fps was always 15 for all routes and scenarios, and for all Nvidia and game settings. I have a fairly high end system and was getting much better fps before. Panning is jerky and slow, in the reguar view and in the 2D map.

Are you in Windows 10? Have you tried leaving you computer in for a while? It might be Windows 10 doing some upgrades in the background.

If your FPS is "locked" in everything (quote: " and for all Nvidia and game settings") then you should unlock it from within the Nvidia control panel. This happens sometime with Win 10. Advise you to update to latest video drivers if you have not already done so (and then check in the Control Panel again). This is not really a Train Sim' issue by the way.

I am in Windows 10, dual booting Insider Preview and regular Windows 10. Same problem in both. I have latest video drivers and I tried rolling back - no difference. I have been fiddling a lot with Nvidia control panel and inspector but nothing makes any difference. What in control panel locks FPS? I don't run any other games so can't tell if it's a Train Sim issue.

In the control panel / manage 3d settings look at the bottom of the list and check that Vertical Sync is OFF. If it is set to ADAPTIVE (half refresh rate) this will lock your FPS at 15 (if you have a fairly standard 60 hz monitor). There are no settings in TS itself that will lock FFS (unless you have been adding start up keys to the exe file - and you would certainly have to know what you are doing to play with stuff like that!)

Not fully true about the game not locking at 15 fps. 15fps is the lowest that the game will display, so if it's lower, you will see steady 15fps.

[mraymond]

Thanks, but setting Vertical Sync to Off changed nothing. No keys in .exe file. PCMark gives a good score so I think it's a Train Sim issue. Downloading Battlefield 4 so I can check against Anandtech reviews. I have I7-4790k and GTX 970 so I usually get good frame rates.

Try to clear game cache (Settings/Tools), maybe it'll help.

OK, that is true of course, but since the OP indicated that ALL of his FPS were locked at 15 (quote: " and for all Nvidia and game settings"), I was inclined to dismiss that fact in favour of something more closely related to a problem with the PC rather than TS. Yet rather oddly the OP indicates in the post above that he "usualy get good frame rates", so maybe there is/was something in the original post that I misunderstood?

It does seem to be something a little complicated at this point in time.

[mraymond]

I meant all my TS frame rates are now 15, for all routes and scenarios, no matter how low my game graphics settings. I always got good TS frame rates until this problem started a few days ago. Clearing game cache did not help, neither did Verify Integrity of game cache.

Check if your PC is using the Nvidia graphics card for TS 2016. Maybe it's trying to run the game on the integrated graphics to save power or something.

[mraymond]

I checked that again. It's set in the BIOS to use PCI-E card. I made sure it was running at full speed when TS is running too. This is mysterious and frustrating. TS is too slow and jerky to be playable at all, and it happened suddenly overnight when I had changed nothing.

[Robbedem]

That's not a BIOS setting, it's probably under power management or something in the configuration menu. Put it on (high) performance.

[mraymond]

I have Maximus VII Formula motherboard. It's set under Advanced/System Agent Confuguration/Graphics Configuration. You can choose to force the display to be from the PCI-E graphics cards or from CPU graphics. So it would not matter what game you are running.

Have you tried this:
Open "NVIDIA Control Panel" > "3D Settings" > "Manage 3D Settings" > "Global Settings"

a. Power management mode - Prefer maximum performance
b. Vertical sync- Off
c. Threaded optimization - off
d. Triple buffering - off
e) Single monitor selected
Try these to see if they make a difference as the power option can interfere with performance.

To Glen Ives you can easily set a fps max figure in TS2016 - Open Steam , Library, Train Simulator, right click, Properties, "SET LAUNCH OPTIONS" type in -FPSLimit=xx, OK and your fps is set in the game - no expert knowledge required.

Sorry, but it is incorrect and misleading to say that adaptive vsync will lock the fps to 15 - that is NOT the way that it works - http://www.geforce.com/hardware/technology/adaptive-vsync.

Some additionl qestions if you are nickelplate on UKTS:
What OS version are you running? Win 7, 8, 8.1, or 10?
What NVidia driver are you using and how was that installed - by you? or via Windows update?
Have you rolled back a NVidia driver by any chance?
Have you tried the games with DSR switched off?
Is your native screen resolution the preferred windows one and the same in TS2016?
