So, at first i tried 'RAM Manager Pro' in 'Hard Gaming' mode and it did work but to a little extent.
then i tried 'Seeder 2.0' and it was much better. Though the game still lags a bit but its playable now and it has option to
enable/disable it whenever i want to play the game. I will continue using seeder for now.
Thanks everyone for your help!
