Persisting input lag after hardware upgrades

Hey everyone,

So I was on here not too long ago addressing my input delay issue. After a longer gaming session, the input delay that I would experience would be very noticeable. It would happen after 3 or 4 matches of Fortnite, or most other games. It would feel sluggish when I aim and move my mouse around, compared to the instant response my mouse would give at the start of playing. To resolve this issue before, I could restart my PC and the input delay would be gone. So I would keep doing this over and over again whenever I would get the input delay. I was told that my CPU had issues with its GHz values, and my power supply wattage was also lower than it should have been. Here was my previous setup:

CPU: Intel Core i5-6400
Motherboard: Gigabyte - GA-H110M-A Micro ATX LGA1151 Motherboard
Memory: Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-2133 Memory
Storage: Kingston - SSDNow UV400 240GB 2.5" Solid State Drive
GPU: Gigabyte - Radeon R9 380X 4GB WINDFORCE 2X Video Card
Case: DIYPC - Solo-T1-BK ATX Mid Tower Case
Power supply: EVGA - 400W ATX Power Supply
Keyboard & Mouse: Razer BlackWidow Ultimate, Razer Deathadder Elite
Monitor: Samsung S22E310H 21.5" LED Monitor

I upgraded my CPU to an i5-7600K, my power supply to a 550 Watt, and I also bought a Cooler Master heat sink w/ fan. I am fairly sure that I installed everything correctly, although it was stressful getting that Cooler Master in. I have been going through my MSI values and doing some Bench Marks and the values are all coming back good. Under the RealBench stress test the CPU did not surpass 65 C, and during normal gaming it floats between 45 to 55 C. The usage values are a lot better than my previous CPU, and I am not noticing any significant FPS drops or slow performance. I float around 120-150 FPS in most games. My GPU temperatures range peak around 90 C during heavy gaming, but I have heard that this is normal. But, I am still getting this damn input delay.

A few things to note, I have tried different mice, monitors, USB ports, etc, so I am fairly certain that there are not any problems there. Unless my monitor is deteriorating due to an issue with heat or the wires, but I have no idea how I would test for that.

I suspect at this point that it is an issue with the motherboard, my GPU, or some heat related issue. My case does get decently hot over time, but like I said, the temperature values are pretty good. This has been an incredibly frustrating issue, if anybody has a clue of what is going on, please let me know. Thank you very much for reading this and have a great day!

Hi, I think it is your ambient temperature of components and GPU reaching a point when the GPU throttles back after a few rounds of gaming. It is not OK to run the card at 90C as it is too high.
I would get another 2x140mm fans on in the front for intake and one in the back for exhaust (if it fits otherwise get a 120mm fans).
Monitor GPU temps, increase the FAN curve and test it out. Does your GPU fan curve reach 100% under full load? Does it ever come down under load? Increase fan speed if possible manually, otherwise your need to either get more case cooling, or need to get a new GPU.

Hey. not sure if you ever got this problem solved, but I am experiencing the same thing and am wondering if you did fix it how you did because it is really messing with my gameplay and I don't know of a solution

Oh hello!

So yes it was definitely an issue with heat and the close proximity of my PC parts. My motherboard is very small so my parts heat quick, being that they are very close together. My GPU is not top of the line either, which doesn't help. I got a big case and that immediately helped with lowering ambient and peak temp. So I would look heavily into your physical setup and keep an eye on temp, while also bench-marking your personal hardware to see what your optimal settings are.

Have a good one, and good luck!

I think rule of thumb is that if the stutter starts occuring shortly into gameplay, you either have really poor airflow or have limited your fan-curve (like I did accidentally to 60%) to something and the GPU is overheating.

I actually had this issue once with MSI afterburner that I set the fan to 60% and the toggles are not always clear to me if they are on or off. They should just label the buttons ON or with a TICK or something instead of lighting up with a brigther color because you can very easily make mistakes in that program (I recon anyways).
