can rtx affect older sims games

@Gothangel Sims 3, SimsCity, Sims4 are optimized by NVIDIA Experience. You will need to upgrade the GraphicsCards.sgr and the GraphicsRules.sgr files to include the newer graphics cards in the Sims 3 - you can find the updated files here: https://simscommunity.info/2021/08/31/must-have-mods-for-the-sims-3-to-improve-stability-and-performance/ -- there are similar mod fixes for the Sims2 to update the graphics cards, you can find it if you do a web search. It has been a while since I updated mine. I never played Sims1 so I can't speak on what you need to do there.

I haven't found any issues playing my games, if anything my graphics are better.
