Requesting Bandicam to add a basic Framecounter overlay that updates by 1 every game frame.

Some of the possible use cases could be: manually inspecting your recordings frame-by-frame to detect frame drops, calculating the duration of in-game actions with ease, or maybe even acting as an accurate timer for "speedruns".
Such a function would benefit the most from being implemented into software that hooks into pretty much every game and graphic API, such as RTSS, MangoHud, Bandicam and the likes.

There's only 2 specific programs capable of achieving this already that I'm aware of:
libTAS https://giant.gfycat.com/DeterminedEmotionalHuia.webm
RenderDoc https://giant.gfycat.com/OptimalBronzeJackal.webm
libTAS has little compatibility with anything and is Linux-only. RenderDoc is multi-platform but it doesn't really work on anything older than DX11. And both can get pretty clunky to work with.

Bandicam already counts frames internally to an extent, so I assume it shouldn't be too much work to "expose" it for the user.

Hi WAZAAAAA,

We have forwarded your request to our development team.

Thank you for your suggestion.

hey just wanted to point out that MangoHud now has it https://github.com/flightlessmango/MangoHud/pull/709

This an excellent and logical feature suggestion. I would be both useful and relatively easy to add.

However, when I read these words "We have forwarded your request to our development team." I lose almost all hope.

If I may pop in with a Suggestion, until it is implemented in Bandicam, you can use programs like Razer Cortex, MSI Afterburner, or FRAPS to show an overall frame count (with stats for drops/etc). FRAPS will save it as a comma-delimited file, Cortex shows you in the app itself (and may save it as a file), as does Afterburner. I believe Mirillis' ACTION can do the same (save stats as a file). These can let you know if you are experiencing issues, until it is included in Bandicam in the future. HTH
