There is no universe in which frame gen would ever be required for Counterstrike. The system requirements for CS are as low as feasibly possible to maximise engagement. Valorant is a better example.
It depends on your base framerate. When your base FPS is already low, Frame Generation just adds more fake frames and doesn't really reduce latency but keeps it pretty much the same.
FG has always been a tool for mid-to-high-end GPUs. It was never meant to magically turn a weak PC into a high-performance machine.
What did you expect... The higher your base framerate, the lower your latency.
Maybe just stop demanding stupid levels of FPS. Remember when 60FPS was cool? Now you have people buying 144hz monitors then upgrading to 240 then 360 the complain they can't get native 4K graphics.
Frame generation can boost FPS by up to 3-4×, but does it improve real responsiveness? Higher frame rates may mask latency and uneven frame pacing, which makes performance harder to judge. It helps on low-power hardware, but native performance still matters most.
