To the kind attention of developers # Re: Performance issue

[335th_GRAthos]

Look guys,

Clearly there are a lot of points there and I can not say that this is a great programming work and everything is smooth as silk, only the HW is the thing that is ready yet and we have to wait for intel, AMD/ATI and NVidia to develop the proper hardware for our flight-sim.

Despite that, we waited for many years and finaly we got our simulation, with an amazing number of things incorporated based on a lot of input from many of us. I even believe a lot of us are surprised seeing how many things got inside this flight sim...
It is a hard core sim and it is A M A Z I NG!
And we should be happy that 1C is giving us so much support and are online fixing things with such speed. Yes, I am happy to have the game as is (I have two versions), had I waited for all the things to get ready I would probably have been waiting for another year...

It is becoming clear that GPUs with less than 1,5Gb RAM are immediately seeing the limit.
Some people proved that there are quick fixes to lower the immense and somewhat uncessesary load of graphics and luckily, the last patch managed to incorporate all that making the game very much playable.

Still there is no SLI (which should considerably improve things) but people try to fly at res 1600x and have demands both in terms of graphics quality and fps!
Well you can not have it all guys, let's moderate a bit the level of demands...

I can fly this game at 3840x but I fly only at 1280x because I want to keep my fps over 50. And sometimes reading the posts here, I have the feeling I fly the smallest resolution anybody ever tried in this forum! (have two 570GTX on my PC...)
1280x and I see my GPU RAM reaching 1200MB (max is 1280MB) so I know there is no need trying to go for more.

To cut the very long story short: Patience is required, if you want to dogfight online, the buildings have to go!!!!!
We had it in the past, when in trouble dive to the buildings (and pray the other guy is running on a 6800GTS...) I do not think it will ever change so I do not see the reason to complain.

Happy Flying!

Hi Athos!

I agree in what you're saying except from this small part.
Back in IL-2 it was only a few cities that would produce real problems with decent GPUs.
Here in all cities that I've flown over I had this problem - not only in London. This means that the extension of the problem is rather bigger.

And by the way, I do not test the game in high resolution

In any case, I'll test again later, setting SSAO off.
Maybe it'll make the difference.

As someone suggested earlier, I've found "Land Shading" to be a big resource hog. Setting it to low basically got rid of stutters for me.

Here are the settings I'm currently using to get the game to run on my 4870 (512MB):

Resolution: 1920*1080@60
Full Screen: On
Model Detail: High
Buildings Detail: Very Low
Land Detail: Medium
Forest: Very Low/Low
Visual Effects: High
Texture Quality: Medium
AA: Off
Epilepsy: Off
SSAO: Off
Damage Decals: High
Buildings Amount: Unlimited
Land Shading: Low
Grass: Off
Shadows: On
Roads: On

Its not completely smooth (when low down for example) but it is acceptable. Finally able to use the game somewhat over england (havent experimented there much).

I do not want to spoil your optimism but I am afraid it will not...


You are right Dolphin, we definitively had less cities in the online wars, but the job was done, same as when we were near those German flaks (Opel Blitz) and the AAA of the battleships, frame show.

In this game the graphic detail of the houses is amazing. Only problem is that for us flying dogfight full real, nobody will ever be so near to enjoy the artistic detail so it is a bad overkill and the biggest problem the programmers have seems to be how to sensibly remove it (or gradually present it).

Anyway, 1,5Gb is the magic number (the min RAM your GPU has to have nowadays...).

PS. @squidgyb: Good to hear that someone does fly smaller resolutions than me after all...

Don't know about this particular forum, but someone on simhq.com was flying at 400x200 or something similarly ridiculous, vids and all

I do agree on the main point though - performance does need to be improved, particulalry for low-mid end system. Whether this comes from optimisation of the code itself, or better tuning of the available graphics settings - I don't know.
