Hi guys. I am having a really strange problem with some games and would appreciate some help in what may be the cause.

See the old thread I made on this here

https://forums.overclockers.co.uk/showthread.php?t=18707112&highlight=startername_tintin82

If you want the short story, basically I was playing the Homeworld remake back in Dec and my computer would go from a prefect smooth 60FPS to a juddering halt after about 30mins-60mins. This also happens with Cities Skylines and Shadow of Moldor

I have tried everything, all my temps are fine, experimented with memory options, reinstalled windows 10 and 7 , reset all over clocks. Nothing solves this. The strange thing is that when the games stutters it only does when moving the mouse or keys. So for example in Homeworld if I do nothing there could be a massive battle going on and the FPS go back up to 60 in seconds, but as soon as i move a arrow key, or the mouse, the fps tanks.

I couldn't find a soulition months ago and finished paying Homeworld and Cities. I moved on and played Assassins Creed Unity, Ryse, Mafia 2, Pillars of eternity. All these games ran perfect without one glitch for hrs on end and I completed them all. No problem for months!

Now I have started MGS5 and boom, back to the crawling frame rate after 30 mins. Required a restart of the game, and then works for another 30 mins before crawling again, rinse repeat.

Please, someone must know what is going on here. What has MGS5, Homeworld, and Cities have in common to do this to my system that other heavy titles like Ryse does not?

Thanks for any help.
 
What are your system specs?

My initial thoughts would be overheating GPU throttling, or games with memory leaks hitting your VRAM limit after a while.
 
Slideshow (1-5fps) is almost certainly a VRAM issue, I used to get the same when running Skyrim modded and hitting the upper limit. Run some software like MSI Afterburner in the background and when it happens, close the game and see what your VRAM usage peaks at, and what it is when the issue happens.
 
Might be a DPC latency issue? You get any sound popping or crackling when it happens? USB driver conflict? The fact that it happens after 30 mins or so does sound temp related. Maybe hot vrms or something else that doesn't appear on your usual monitoring programs

OK just happened again, VRAM was showing 3172mb. Page file was 9136mb

I have a 980ti 2500k at 4.6Ghz

Nothing audible heard in that regard. Very strange it is only in some games, as I said it has not happened in months until I started MGS5.
 
What power supply are you running?
Just wondering if this is hitting a temp issue or something, and at that point it is struggling to provide enough current to the GFX/CPU. Perhaps it is a 5V rail issue as that will also be connected to the USB ports through the motherboard?
 
I have a 1000w EVGA, run with the fan on economic mode.

I think it's something like what you are saying. Something overheating somewhere.

Would it be worth getting another psu and testing? It is a lot of hassle as I would need to buy one and then return.

And how much VRAM does your card have ?

If the 3172 figure is vram usage then that is a smidge over 3GB and could well be the problem.

Can you lower the resolution you play the game at and re-run the test.
 
Well it's not VRAM if it's the 980Ti. 4.6GHz is a hefty overclock for a 2500K, perhaps that is overheating and throttling.
 
£20 to whoever can can troubleshoot this problem. I do not know if this offer is against forum rules so please excuse if it is. This is the most frustrating PC issue I have ever had, so will gladly pay for some expert advice.
 
I would try the following:

- remove all the dust from your tower. If you don't know how to, have someone else do it
- do a fresh win7/10 install on a different hdd, maybe a portable one, install the game there too

If that doesn't work, take it to a pc service, show them how to replicate the issue. They will test each component and that will probably reveal nature of the problem.
 
If things were working fine before you upgraded to Windows 10 (which I think they did?) Then I'd probably just roll back to Windows 7/8 whichever worked fine before.

It might be an idea to update the OP with a tl;Dr of the things you have tried so far, as most people like me will probably just skim read the old thread :)
 
I noticed it around the time of upgrading to W10, so rolled back to W7, no joy. Then did a complete format and installed 7, same issue. Format and install of W10 same issue.

It is just so random that it only happens in a few titles that being

Cities Skylines
Shadow of Moldor
Homeworld
MSG5

Part of me thinks its a hardware issue, but then why does it only happen in these titles and not for 3 months when I play loads of other games?

As I have said before if I dont touch the keyboard or mouse the FPS rockets back up to 60, but as soon as any keys or mouse is touched then it plummets, requiring a game reset, then its fine for another 30 mins.
