Experiencing lag/latency in online games

Hi,
I've been experiencing really big lag spikes and high latency while playing online games. The problems only developed in the past month. I can browse the internet and download games fine. My internet speeds are 18 down and 8 up which I think are pretty good. I'm using a wifi card. Here are my specs:
Tech Support Guy System Info Utility version 1.0.0.4
OS Version: Microsoft Windows 10 Home, 64 bit
Processor: AMD Ryzen 5 1600 Six-Core Processor, AMD64 Family 23 Model 1 Stepping 1
Processor Count: 12
RAM: 16316 Mb
Graphics Card: NVIDIA GeForce GTX 1070, -1 Mb
Hard Drives: C: 255 GB (74 GB Free); E: 1862 GB (1007 GB Free);
Motherboard: ASUSTeK COMPUTER INC., PRIME B350-PLUS
Antivirus: Windows Defender, Enabled and Updated
Any help would be greatly appreciated

 

Since you have the good configuration of the system, the reason behind the lag could be:

• The system might lag because maybe the system is not fulfilling the game requirement.
• Reducing the processor workload may help.
• Consider Your Network
• Keep all drivers up to date
• Defrag the hard drive

 

Hi, GeForce says that my drivers are up to date but the techguy system thing still says -1mb. Any Help?
