frame timings Frame timing issues

[borotech]

Hi all, I originally posted this in gaming but I think it may be more appropriate here. 

 

My specs are:

 

Ryzen 7 3700x 

GTX1660 Super

Asus Prime X570P

16GB Corsair Vengeance 3600mhz (2x 8GB) 

500gb sabrent m.2

Corsair CX650M power supply 

 

I have been experiencing frame timing issues in CSGO... particularly at high frame rates. I will have really good FPS 280+ consistently but about every 10 seconds or so my frame timings will shoot from 3-4ms to 50+ms for a brief second, resulting in stutter. When I have enabled V-Sync to limit the FPS to 60, the frame time spikes are less extreme and less frequent (staying at 16.7-16.8ms - occasionally spiking to 25-30), but are occasionally noticeable (not just by looking at the RivaTuner overlay). What can I do to troubleshoot this as in a game like CSGO this can be a really big issue?

 

Temps, clock speed, fan speed, CPU speed and temps are all normal, and there doesn't appear to be anything unusual happening in HWiNFO or MSI Afterburner monitor corresponding to the frame timing spikes. 

 

Steps I have already tried:

Uninstall and reinstall latest Nvidia drivers. 

Switch off DOCP, returning ram to stock 2666mhz and timings.

Tried V-Sync both off and on. 

Enabling low latency mode in the nvidia control panel (made it worse)

Unplugging other devices from the extension lead powering my PC. 

Tried lowering settings. 

 

Is there any chance that my cheapo extension lead could be causing this, giving uneven power deliver (although I thought there were capacitors in the PSU and MB which were meant to mitigate this?)?

 

Any help would be greatly appreciated as this is very frustrating as this PC should be able to easily play this game no problem. 

 

Thanks

there are two main factors when something is not getting a signal the length of the cable and the amount of adapters on the cable. so I would say that you should try getting a new more expensive and longer cable and see if that solves your issue. it could also be your monitor settings are not correct since most now are connected by and HDMI/display port cable making them completely independent of the computer.

what is your monitor you are using, sometimes its not with the GPU but with the monitor

To be fair it isn't a gaming monitor. I usually use my PC for professional work (CAD, Premiere, Photoshop, Blender), but play games in my spare time. I thought it might be my monitor but I am seeing the spikes in frame time on Riva Tuner Statistics graph?

Thanks for your help. I'm using a DP cable. It still doesn't explain why the frame times on RivaTuner statistics OSD graph is showing the spikes in frame time. Wouldn't his only happen if something on the PC is causing it, not the monitor?

 

Thanks

honestly, I have no idea. I say yes because if the computer is not on, then no screen anyway/ but I was just guessing because sometimes the monitors like to act up a little. I am using an older model TV as my computer monitor so I only need 1 so I am limited to the refresh rate of it.
