I know, this was asked so many times but I never found an answer to my problem.
The problem is, that when I play Oblivion the performance is quite good. But if I´m in Market District or in many other towns it starts to lag. I know that it is an old game and I have installed a huge ammount of tools to fix that, optimized my textures and also my INI (OSR, 4GB patch, EngingeBugFixes, NVAC, Ordenator for fixing Textures). And I don´t have that many mods. Just QTP3, Bromets SI Textures and some smaller mods. Just like a bit over 20 plugins or so (I had much more on my old System and it run better there.) The thing is, I don´t know why... There are some videos showing Oblivion 2018 Textures (or something like that) which have really stunning graphics with 60fps everywhere... Is it due to the Ryzen Processor? I mean yeah it hasn´t the best Single-Core-Performance (which is what counts for Oblivion), but the SIngle-Cores must be better that the ones from, let´s say, 2008... So it should no problem... Are there any other tips? Or tweaks or settings I should set? I really can´t understand why some people can play it so nicely and I have lags with a Ryzen Hexacore and a GTX 1060 6GB...
