Maximise Performance option tanks FPS

Hello there, hope your all well.

I recently had an issue with low FPS in a game I had not played in a while (FrostPunk on Steam). After playing for a few minutes the game would drop from 100fps+ to about 15-20fps. I discovered that reloading the game or even just loading a saved game would return it to 100fps+ but always after a few minutes it was again back at 15-20fps.

A lot had changed on my system since last playing it, new motherboard and graphics card, lots of game, app and driver updates. I looked across my system for settings that might change the situation but nothing appeared to help. I reported the issue to AMD as I thought it must be a graphics driver problem as anything using just the CPU appeared to run normally.

I then told AMD that it does not appear to be their drivers. I discovered in Avast, going to Performance > Do Not Disturb Mode > selecting the game in question and unchecking the box “Maximise Performance”, returned to game to normal, and in fact it provided a fps boost in most other titles.

Therefore I conclude there is an issue with “Maximise Performance” option in Avast(free). Has anyone else had this issue? Is there a way to stop Avast applying that specific option to every app/game?

My system…
CPU: AMD 3800X (@stock core clocks, infinity fabric @1800)
Memory: 32GB RAM (@3600)
Graphics: AMD Sapphire Nitro+ 5700XT SE
Motherboard: MSI MAG X570 Tomahawk WiFi (bios 1.15)
Storage: Win10 Pro on Seagate Firecuda 520 1TB NVME using PCI4.0, Games on Seagate Exos 8TB

  • Which version/build of Avast Free…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Hi there,

Software…
Avast Free 20.6.2420 (Build 20.6.5495.561)
64bit Windows 10 Pro 2004 Build 19041.388

I don’t have any other AV running. However I do have a copy of Malwarebytes Free (4.1.0.56) set to manual so it only runs when I want it to. Windows defender is used occasionally in the same way.

Hope this helps.

Follow instructions: https://support.avast.com/article/33/ and post the File-ID and/or name of the Support-File here afterwards.

Hi there,

I’ve just realised that Avast updated itself recently and the version I mentioned was not the version in use at the time, it was the previous one, don’t know the version number of that one. I keep the software as up to date as I can. However I’ve still done as you have asked. Avast file ID is CM421

Also… On the current version I re-enabled maximise performance to check if the issue is still happening and there is no drop in performance as before. Maybe a problem with files from previous version or similar?

Not sure whether this has been a waste of time or it will happen again. ??

Thanks,

You’re welcome.
