Hello,

Recently I purchased a Acer Laptop Aspire E5-573G-75B3.

Here are the specs:
Intel Core i7 5500U (2.40GHz)
8GB Memory 1TB HDD
NVIDIA GeForce 940M (4gb dedicated memory)
1920 x 1080
Windows 8.1

Even on lowest settings the laptop can barely run even source games like TF2 and CSGO. Single digits fps (unplayable) while unplugged.

What I have already done:
-Switched to High Performance power plan

How can I make my laptop run better without being plugged in? Even my older laptops have been fine running games without being plugged in.
 
Solution
Go into the BIOS and look for speed and power options there. You can also contact Acer and find out how to turn off switching to lower speed on battery power for your model.
