If a game was built from the ground up around path tracing and the developer was content to essentially lockout anyone that didn't have atleast a mid-range (2080) Turing card (or just look rubbish on anything else by forgoing any special case support for traditional shadow mapping and other global illumination hacks, etc.) then it would be possible to make very good looking games that ran at very playable framerates at upto 1080p and OK framerates to 1440p that used ray tracing for all lighting/global illuminations, reflections and caustics, etc.
Yes there are some compromises with the current implementations reliant on the performance of the denoiser to produce effects anything like proper ray tracing at viable performance levels but for the most part the issues are liveable with - the slight delayed fade as light propagates over several frames instead of instantly on big changes is fairly organic and largely goes unnoticed once you get used to it.
Quake 2 is actually a better benchmark than people give it credit for because path tracing is not particularly troubled by increased polygon count or scene complexity and some of the performance can be offset by removing traditional rendering techniques used to make things like realtime shadows work without ray tracing.
EDIT: 4K Quake 2 RTX on my 1070 makes the GPU cry LOL - the framerate counter is a lie - it does 7 FPS at 3840x2160 with 50% resolution scaling and 2-5 FPS at 100% scaling:
It also seems to stop updating the lighting properly sub 10 FPS - there is some noise and lack of colour detail in the screenshot that isn't present at 1440p.

Is it easy enough to mod into the games or a lot of faffing about?
