Hi, I have an amd a10-5745M quad core APU with Radeon hd graphics 2100 Mhz 6.00 GB RAM in an hp envy laptop. I'm having issues with arma 3 fps being very low. When I start the game it's at about 45-55 fps and when I start single player it drops to 30-10 fps. After playing for a minute or so it won't go higher then 20 fps and slowly keeps going lower til about 10 fps. And when it comes to multiplayer it has never been higher then 20 fps and can go as low as 3 fps. If anyone has any solutions it would be much appreciated. I've tried already different launch options found online and gpu frames ahead to 1. Nothing seems to work for me.
Your laptop is woefully underpowered to run Arma 3 at any kind of playable frame rates. Its most likely overheating and throttling itself so it doesnt fail. Get better hardware if you want to run that at playable rates.
