This game works, when it wants

[Kankkis]

Can somebody tell me why game performance is different sometimes.

Let me explain:

I just booted my computer, launch steam and game(nothing else), going to crosscountry mission, my game is reallysmooth, full 60 fps and really smooth on very low level flight

Next time when i launch game and steam(nothing else), going to crosscountry i got max.40fps and when flying at very low level, game is it not smooth, there is rubberband effect, i mean no stutter but its not smooth like when i got steady 60fps.

Next time it can be good again and so on, this is really weird thing, any other with same problem. I'll use fraps to check fps. Usually first try if i see it's not smooth i quit game and go into windows and restart the game without booting it can be smooth again.

I just start the game on same computer settings, same mission and time, all is same, sometimes it's not working well and sometimes it's smooth and then it's really nice to fly.

Why the game textures is loading after mission starts, really annoying that stutter, i must pan around and wait to get it smooth, first sim when i see something like that. Sometimes in MP it can take very long with that starting stutter.

A temperamental game..., no serious, maybe RAM. This Sim is a monster always hungry of RAM and without limits.

Use an old version of fraps, the last patch killed the later versions.

Good point.

Interesting that they went with a 32 bit game... Hmmm 64 bit anyone?

I've seen similar texture loading in batches (gradually going from low detail or even completely missing textures to high detail) when flying FSX at very high detail settings with 3rd party scenery add-ons on a friend's PC, that's how i identified it as the main culprit for stutters and low FPS and reduced my texture size appropriately.

I think that it's a two-pronged deal here. It might be possible to further optimize the texture loading system and if/when we get a 64 bit executable have it utilize more RAM, swapping textures between RAM and GPU instead of hard disk and GPU and alllowing us to run higher texture sizes. It might also be possible to optimize texture size in bytes without compromising quality but this is a more long term work.

In the meantime, dropping textures from original to high or medium resolves a lot of problems and results in smooth gameplay, at least for people not using dual GPU setups.

This is just from memory but didnt Luthier once mention the landscape loading in blocks of 100KM or something?

Yeah im using fullscreen, i got better performance with pseudo because then it disable crossfire, there is plenty of games what doesen't suppot crossfire but this is first game with crossfire is poorer than 1gpu same card, CRAZY. I mean crossfire doesen't need straight support to work faster than 1gpu same card, this is first game when crossfire is slower than same card with 1gpu.

With pseudo i cannot use vsync and i got terrible tearing, this is reason why i use fullscreen.

Texture loading after starting a game does happen in some games from time to time, although it is rare these days.
Not that it should really matter, but have you checked to see that for example your antivirus isn't performing backround tasks or another quite intensive program isn't running in the backround?

Yeah, tested it without antivir and other programs, i can live with texture loading but it's somehow weird, even when y look planes in menus, i dont remember menuname but even there plane textures come in very slowly

Game is good looking but i think performance is not near what it can be.

All other games is very flyidy on my machine. RoF with supersampling, A-10 allmost max setting and so on.

When we had good performance we have diamond in our hands and i believe that the devs is making their best and we have very very good sim.
