I have a AYANEO Air Pro (AMD Ryzen 7 5825U) which in theory is a good gaming PC.
I am building a 2D game and am testing performance by having it set to a fixed frame rate of 120.
The game runs absolutely fine solid @ 120 FPS all day long! Yipeee!
BUT! then some days, the same build (packaged) will struggle and hover around 90-113 FPS!
Sometimes it may recover back to 120 FPS or it just won’t.
Sometimes a reboot will bring it back, sometimes a reboot makes no difference.
What’s going on? Is it Windows or is it because my PC only has 3 GB VRAM (which I can’t change)?
If it is VRAM then why does it on some days run awesome?
I have no anti-virus installed (other than Windows Defender) - no other apps open - all settings maxed out for gaming etc.
I’ve done all requirements within UE config to get the most performance.
