Hello,
can you obtain a monitoring program like hwinfo or hwmonitor (or anything else similar by your preference)
and obtain the following information while playing Arma and FO.NV:
- GPU and CPU temperatures, especially maximums
- GPU and CPU utilization, in %
- GPU clock rates, maximums
Besides those, look into the following:
- do you have the latest drivers from AMD website for your GPU? if not, go get them
- do you have power settings in windows set to best performance?
- what about power settings in CCC?
- Is your harddrive being read excessively during the time when lag occurs? (you can check this in the resource monitor)
- Do you have any background programs that are running at the same time that could be taking up your HDD or CPU time? if you're not sure you can try gamebooster
Lastly, were these games always running like that or did it only start happening recently?
if it was always like that, what settings are you running the games on?
if it happened recently, do you recall installing any new software or hardware on your laptop? how about physical damage, didn't drop it anywhere?
