To be fair with CS1 and mods like 81 tiles when you got a population of 100,000 the fps would tank and go around 20fps regardless of system spec or game settings. CS1 was responsible for me getting 64GB ram on the newer system i built at the time. I fully expect it again on CS2 but I come from a time where Crysis ran at 15fps and was great on my 7800GTX
