Hello guys,

as I mentioned in the title, my problem is that when I play games (doesn't matter what, even hearthstone) and I'm watching Youtube or Twitch streams, I'm experiencing terrible issues like huge FPS drops. I don't really know where could be a problem, because I did a fullscan with malwarebytes and spy-bot in case of finding some malware shiatz, but nothing found. I've tried to change a browser from Chrome to Firefox, helped little bit, but it's still bad. My CPU is i5-4670k, GPU GTX970 and I've got 8GB RAM. Kind of overkilled rig for experiencing issues like this right or am I wrong?

Hope you can help me bros.
 


When I bought it, I don't really know, cuz i played without GPU for like 3 months, so I wasn't able to play any good games. But then I bought the GPU and started buying some better games like GTA 5, where I have a lot of problems with stability too. When I played the game everything worked just fine on 80FPS/UltraSettings and then boom, game was getting a lot of FPS drops, it's not better now... But I was like ''No, it must be something I did by a mistake'' ..Well, maybe no. So it probably slowed down in one day. And if I have to say something about playing and watching stream, it wasn't so good any time before.
 
Did you made any changes, hardware and software wise, to the PC right before it happened as far you can remember?

I'm thinking about:
- BIOS/UEFI settings (like voltages and clock speeds)
- Did you try to overclock with a third-party software?
- Driver updates
- Motherboard update(s)
- Did you enable v-sync in the game? (this will drop your fps to 60fps, which is the max fps a standard monitor with 60Hz will get)
- Do you clean your PC hardware wise?
- Do you clean your PC software/kernel wise (with CCleaner and iobit uninstaller for example)?
- Do you perform any maintenance at all?
 


I can't get voltages and etc right now, but it should be on 1.25V. Only my GPU is overclocked with a asus software, but with predefined mode. Drivers are always up to date, I'm that kind of guy that loves his PC and wants to have everything working just fine. So yes, I do clean my pc hardware like once in a single month. And yes I do clean my software with CCleaner like once a week. I use v-sync in games where it works good, not in games like csgo.
 


What resolution are you trying to play at? Whats the refresh rate of your monitor?
 


1600x900 60Hz is the main one, the second one is Sony Bravia TV 1920x1080 should be something around 100Hz maybe more.

 


Are the FPS drop noticable on both monitors? Or just 1 of them?
 


Actually it is more likely noticable on the main one. Because when I play GTA, I play that on TV (changing that on main screen). And if I play games like HearthStone, I play them on the monitor and the FPS drops are noticable in games (main screen), not on the second screen.
 


Tried swapping cables?
Did you check task manager if something is eating your processes, RAM or C: drive? (while the FPS drop is occuring)
 


Well my monitor is VGA switched to DVI with reduction, because my GPU doesn't support VGA. And the television is via HDMI so I can't swap them.. Yeah, I tried to - it was the internet browser and the game ofcourse, I don't know about any other process. Ram is always on like 4-6Gb usage, CPU 60% while watching stream and playing a Hearthstone, but then woah - FPS drop inc and the CPU is on 100%.
 


Is the fps drop out of nowhere, like suddenly unexpected and random or is it every time once you start gaming while watching twitch stream/youtube vid at the same time?
 


Well it's hard to say because every time I start game and stream/twitch it works at the first time, but after a minute or so It's starting to get laggy. Mainly when I'm on turn and I have to play cards or when I play FIFA and I decide to play youtube songs while playing, the whole game is laggy after like 1 or 2 minutes of playing and when I mean laggy the lags are huge. I'm thinking of overheating right now, what do you think?
 


Well you could run a software to check it. I always recommend using CORE TEMP
It show a minimum and a maximum down below, so u can let it run while you're relaxing and/or game while listening to youtube.

Then check the maximum temperature after 20-30mins and let me know
 


I'm sorry about a little bit too slow reply, but I did some research with core temp. Everything bad I saw was that the CPU freq. was jumping from 3800MHz to 800MHz.. So I disabled C-States and overclocked cpu a bit (4200MHz on 1.2V).. System is stable but it still keeps jumping from 4200MHz to 800MHz, maybe that's the problem. I don't know what to do now. Max temps were like 80°C (fully load).
Little update: I just set the power options on High performance and it stopped throttling down, so it's on 4.2GHz (stable). CPU Usage in Task Manager now looks 100%better. I'll let you know, if the games are still laggy.
 


That's TurboMode, which lets the CPU rest when it doesn't need 100% (all cores).
It's partially to save energy and temps.

Basically it seems TurboMode on your CPU is not working correctly, as its scaling its Ghz down when it actually needs more..

Turning it off might work and hopefully it will. Just keep an eye on temps :)
