Gtx 770 Stuttering! Help!

[Arizona]

GTX 770

Coolermaster 550 psu

8 GB Gskill Ram

Fx 8350 BE

1tb HDD 

ASrock 960gm u3s3

Windows 7 64

Upgraded my system from a GTX 650 Ti to a GTX 770 2 GB OC PNY and I get severe fps drops/ Usage drops in any game I play. I've tried tweaking settings, Full screen on/off , V Sync on/off, Installing new drivers and making sure to remove the old drivers. Gpu is not over heating, it gets to about 65-70 C max and the cpu has never gotten above 50 C.  Don't really know what to do at the point :\ The PSU is under the recommended and I am aware of this, that is the last thing I have to check but currently cannot get one till next week, however ive seen posts where people are running 780s and 770s off 550W and 500W Psu :\ Image is after playing Far Cry 4 for a bit. It runs 60 fps then drops over and over again.

The gpu usage clearly hits 99% constantly. That's why you have stutter. You gpu is constantly unable to cope with 60fps so you get frame rate dips. When you are not synced at 60fps you will get lots of stutter.

His GPU usage is clearly NOT at 95%+ the entire time. I think you typo'd or something....

 

It should be close to 95%+ the entire time, those GPU usage drop spikes you can see are not normal.

[Arizona]

Correct. The thing I'm confused about is if I put everything on medium settings or even low settings, it'll only go to about 60% usage and then dip to 30%, no matter which settings I use it dips. Even on League of legends I go from 200-300 fps to 20-30 on any settings. That's whats confusing :\

[orangecat]

Far Cry 4 has performance issues from what i know so try another game. Also try reinstalling the drivers and clean your settings that might help.

[Arizona]

Yeah thats what ive heard but its also doing the same thing in BF4, LoL, and Grid Autosport. Same pattern it will continue as normal and then dip down in usage and  become unplayable

I didn't mean literally but even 30% of the time is way to much if you are aim for a smooth experience.

Still don't understand what you mean... 30% of time for what?

/Maybe I need to sleep/refresh my mind to understand, but you lost me with that statement, as it doesn't co-incide with your previous GPu usage post either, not the way you word it.

Have you tried different driver versions? Rollback to a previous one and see if it still happens.

May need to OC that CPU to limit further issues (if this is the problem)

[Arizona]

I havent tried to roll back yet. Is there one in specific I should roll back to? do i just go to the nvidia website and look for the older drivers for my gpu?

I'm not a Nvidia user, have not been for quite some time, when I build a machine I generally grab the latest and be done with it.

 

But I'm 100% they would have their previous on their site, just pick the ones before the latest, and the ones before that, just in case it happens with your rollback too, best to try a few of them, and if it happens to all, something else is amiss...

 

You also should quote somesones post or they will not know you replied, the forum will send them a notification when you do.

oh ok thanks for the heads up. im gonna roll back my drivers and come back with the results!

rolled back to 340.20 i believe, and same exact thing. Gpu usage drops up and down :\

I'd look into Overclocking the CPU first, then if not solved (or better), move to the Intel i5 platform.

Sucks to say it, but, thats just the way it is.

I would need an aftermarket cpu cooler to overclock, cant get one of those either till next week unfortunately. its clocked right now at 4.0 would i be able to overclock it to 4.1 or 4.2 with stock fan? its only getting to 40 C right now

I'd leave it as is until you get a better cooler, while you may tweak further and push to 4.1-4.2 with stock cooling, and is a great learning experience, I'd wait then do it with proper cooling methods in place.

[Arizona]

Processing speeds never go past 90 percent though so I doubt it's bottlenecking.

Whether your at 90% or 40% CPU usage in Gaming, the amount of Instructions Per Clock cycle (Or IPC) is the limiting factor.

Having a higher CPU usage (90% + ) can even limit you further if the System is starved of CPU power.

But when not starved, and having plenty available, the amount of processing power (at any usage level) needs to be good, and it's currently not good enough on AMD FX processors in CERTAIN games where a better CPU with better IPC is needed, call it bad optimization or whatever from the games point of view, but thats just how it is.

 

IPC @ 4.0Ghz will be increased with the OC to 4.2-4.4Ghz, regardless of the CPU usage.

Hopefully with an OC, the IPC improves enough to not limit your GPU usage as bad as it is.

oh i get what you mean. within this week ill be buying a 750w psu and an evo 212 cpu cooler. is there a chance at all do you believe that getting that better psu will do anything?

Hard to say about the PSU..

I myself would, 550w is enough for most people with your setup.. But when Overclocking comes into play, it skews expectations too when CPU is using more power (4.5Ghz may need more voltage compared to stock and that will raise power), and your new GPU with higher usage, will use more power too (pretty sure)

 

I'd get it, it's not like you can't keep the 550w as a backup, or make another machine with it, or give it to someone else with less.

 

Evo212 - Should suffice and do the job for up to 4.2-4.5Ghz, anything more and it may not be good enough...

Im asking because ive never seen the power % go past 80 on this gpu. the usage is 99 and drops but the power has never went past 80. so im thinking that the psu is not giving it enough power.

I have/had the same problem with i7, overclocking makes it less worse, but needs a huge overclock to solve the problem.

I´m speaking of a clock of at least 4,8Ghz the more, the better.

Without overclocking: Disable all programs in the background that are not needed, msi afterburner, a origin game with steam overlay etc.

And try this:

Desktop *rightklick*-> Nvidia control center ->3D settings ->Global settings -> search for "Shadercache" set it to "DISABLE"->search for "maximal limit of prerendered images" set it to "1". If you have cpu hungry games, you can specify that game in the nvidia control panel right to the global settings tab and search your game.

 

If that does not help, activate v sync

I just put in my old cpu (phenom ii x4 965) and the stuttering stopped. The gpu usage is constant.Now I can play almost max but can't quite hit max because of cpu hitting 100% usage. On my fx 8350 it hits about 45% usage while game is stuttering.

While I have NFI if this will help, or if you've tried it - Disabled core parking on the 8350?

Some games do love it, some don't benefit, best to test it

"If we didn't see real and substantial performance gains after disabling core parking, we wouldn't have authored this utility."

 

Info on Core parking

Core Parking is a sleep state (C6) supported by most newer x86 processors, and newer editions of Windows. Core Parking dynamically disables CPU cores in an effort to conserve power when idle. Disabled cores are re-enabled as the CPU load increases once again. This technology is very similar to frequency scaling, in that it seeks to throttle the CPU when idle.

 

The problem is that Window's default power profiles are configured far too aggressively when it comes to core parking, especially on workstations. Their interest was in conserving energy, even if this meant marginally decreasing performance. A number of complex parameters control when a core should be parked, and Microsoft tuned heavily towards power savings.

 

The core parking settings in Windows are implemented as parameters of power plans (aka power profiles). That means you can, for example, disable core parking for the High Performance power plan, but leave it enabled for other plans. And that is exactly the desired tweak for most users: disable parking only for high performance power plans.

 

Empirical evidence shows that disabling core parking can make a real difference in system performance.

There are many factors that will determine how efficacious it will be for any given system, including the CPU type, application load, and user behavior. However, we find that Windows is often over-aggressive in its core parking, resulting in excess latency as cores are unparked to accommodate bursting loads (the most common type of CPU load).

 

In our tests, we've found AMD processors benefit most from disabling core parking. This is perhaps due to the dramatic difference in the way AMD processors share (hardware) computational resources between logical cores.

Microsoft optimized for Intel's HyperThreading, which has much less capable secondary cores. AMD's secondary logical cores are near full CPUs.
