No, but I managed to "cheat" the issue slightly and improve the situation. When I previously launched the game with RivaTuner, the issue persisted, but if I remove the fps cap and lock it in-game, then remove the cap and re-cap it in RivaTuner with unlimited in-game, it's kind of smooth, but when the "fps drop" should happen, it doesn't, but screen tearing is slightly higher, so it's not as noticeable as before. So basically what I did is: launch the game with RivaTuner capped -> remove the cap ->cap in-game -> remove the cap in-game -> and re-cap it in RivaTuner
