Yes that must be the problem as you mention that, I am also working on the Portsmouth Direct, just so when I get bored of one route (which can be tedious for a scenario pack) I'll work on the other for a bit, then back to PDE etc etc.david1 wrote:I don't have a super PC, was quite high spec but now TS2019 is more demanding, mine now is under recommended specs on CPU 2.70 Quad, runs fine apart from lags a little as CPU struggles send data to GPU where scenary is dense, I have done a few scenarios using lots of quite demanding stock class 313,321,90 and AP mark 2 along with 47,57,86,87,92,150, the only time Euston lags is when I place lots of AI in nearly every platform, think the problem could be the class 390 as it uses a lot of resources I have heard as I don't have the new version, if you have the old one I would recommend using the old one for AI traffic, I have found a similar problem with Waterloo to Portsmouth classes 444 & 450, by using the older versions I almost double the frame ratetubemad wrote: I guess making a Birmingham to London scenario with realistic AI is only for super PC's
I did one with the PDE 450/444 as AI, and Woking all the way to Waterloo was very bad on FPS. Having seen your post above, I did my next planned one from Hampton Court to Waterloo using the 455, but used the old Class 450 and 444, and wow what a difference! Even Clapham was manageable and Waterloo FPS was much, much better! So now I'm using the old 450/444 for AI on the other scenario's, and shall use the PDE one for player only.
