I'm trying to diagnose performance issues and could do with a little help, please. There is a growing list of games that I have that perform with awful judder to the point where they are unplayable. I originally put this down to a quirk in certain games, but now the list is growing to the point where I'm thinking is there something wrong with my system?

Some games are silky smooth, which just confuses me more!

I'd be interested in any thoughts/suggestions you may have. I'll post some video in the next post that hopefully will show the issue.

System spec:

2700x
Z470i
1080ti
X34a @ 90Hz
Frame cap @ 88 (Rivatuner)
Vsync ON in Nvidia CP
Vsync OFF in game
 
Here's a video of Dishonored 2. The textures shimmer like mad and there's a horrible judder when panning the mouse around. I've lowered all the settings to rule out a cripple setting. I've tried just about everything to smooth this out, but having no joy.

Update: dropping monitor refresh to 60Hz and enabling Vsync in Nvidia control panel fixed this.



Here's Hunter:COW - set @ 60fps with everything at low and the judder is awful.

Any crashing or just poor performance?
Use MSI afterburner to monitor the in game performance of GPU/CPU, post results.
Memory tested stable? (ramtest and/or HCI memtest)
Give the setup you should not be having issues with anything.

No crashes. You can see by the overlay in the video that FPS is solid 88 with CPU & GPU having bags of room to spare.
 
what drivers are you using?

Can you try turning off the Frame cap and Vsync and see what happens?

EDIT: I am just wondering is it a problem with the monitor, Can you also try running it at 60hz?

Latest driver; 417.35

I'll try the other suggestions and post back, when you say running at 60hz do you mean capping at 60 or lowering the monitor to 60Hz?

I am going to also suggest you roll back to the 388 drivers. Every driver since the 388's have been giving some kind of problem.

Just mean lowering the monitor to 60hz, that's it's default isn't it? 90Hz is overclocking it? It's supposed to be able to overclock to 100hz no problem, but just in case it is causing a problem try 60hz.

Your Acer monitor should have an FPS refresh rate monitoring setting so you can check whether the refresh rate is varying in line with the FPS and hence that Gsync is working. It is more reliable the Gsync indicator in the Nvidia control panel.

This appears to have solved it. I've dropped the refresh rate to 60Hz and have Vsync on in NCP (tearing is awful with it off).

I hope this is game specific. I'll have a wee play for a while to ensure this was the issue, and then I'll test with the other games I'm having issues with.

Cheers @melmac

The only reason I said to try the monitor because I have seen that mouse judder before with an overclocked monitor. If this does turn out to be the cause of the problem, does that mean your monitor is faulty? Aren't those X34 monitors supposed to be overclocked?

I hope it's like you said, that it's game specific thing and not a monitor thing.
 
@melmac Yea, I'm not sure what to think of it. I think the monitor is only guaranteed to run @ 60Hz so RMA is probably out, but on saying that some games run 100fps silky smooth so maybe it is just game specific. Another game that acts up similarly is Hunter:COW. I'll need to see if this fix applies there, too.

Will report back, but beer is flowing and wife wants to watch a movie. :)
 
The next game I've tried is Hunter: COW. It's a juddery mess, unfortunately. I've tried the 60Hz thing that worked with Dishonored 2 but it's still horrid, so hoping we can suss the reason. I suppose the positive is that the 60Hz fix was unique to that one game and not an issue with the monitor (bear in mind, there are games that run perfect 100fps), but on the downside there's still an underlying issue here.

I'll post a video later and hopefully you can see the issue I'm having.

Get rid of the Rivatuner. It's another layer of software. I can't see the point.

Everything else looks good.

Are you overclocking your monitor? That could be the problem as well.
