ground lag stuttering(beta patch)
 

So, m havign this huge issue with my current installation of alpha/beta patch.

i have 70+ fps over England (60 with vsync) yet, dispite my fps i see the ground lagging and stuttering. which is strange because my bullets and pother plaens move fluidly over this stutering land.

so picture a stable fps and the game moving at 60+fps, but the ground only moving itself at 15-20 fps?

to reproduce this issue, fly over england at 500 meters max, and look down to the ground, the easiest view is looking at the trailing edge near the cockpit (low5/7 o clock) zoomed in, and watch stuff passing below you stutering.

settings:
maxed out graphics.
7870 i5 2500k 8gb ddr3

tried to play around with settings, specially vsinc ssao and AA. no joy.

Are you sure that when you look the ground you still remain at 60 fps ?
I get 60 when looking up, but about 20 when looking down... that´s "normal".

no. i set the fps counter, when i want to do the test. and the minimum sticks to 50 or so.

also this is constant, not a happens once in a while.

I get 40-45 with looking down like that. The beta patch has improved the stuttering quite a bit. I imagine this will be a big problem with the Battle of Moscow flying an IL2. Maybe the snow instead of grass will improve the stuttering.

I see you have a similar pc to me except you have a better graphics card .But I am getting twice the fps as you!
What resolution are you running? do you use ingame AA or FXAA?
Are you against lowering your res to 1360x turning off ingame AA and using FXAA?
Cause you may be able to double your fps

Will test now.

Didn't get a problem, can you confirm this happens both in and out of cockpit?

I have had a similar feeling but have to test it more. It sounds like what happens when you do multithreading that many seems to think is an easy task... The landscape object handling /texture loading etc is on it's own thread now (?) that does not run in sync with the main render thread? If you sync every frame the whole game will stutter so when the landscape thread cant keep up this is what could happen? The main render thread "pumps on" but the "landscape" is not able to keep up?

Just guessing...

You mean Intel Hyper Threading ?

Yep, can be a problem, Hyper Threaded cores are not a physical core so they are slowest than a physical one (in short).

But my guess in all this is that its the know issue of the grass and trees code not being optimized yet :

The patch in his current state brings smooth play in high and medium altitude, but there still hick-ups at low altitude due to the not fully optimized grass and trees yet.

Try it at a higher altitude... say 1,000m and see if the stuttering still occurs

what is your video card?


and MAX SETTINGS ? well, best of luck for anyone there. One of the all times greats of frame rate killing is trees (running lots of them), every sim has suffered from it

@wolf_rider

my gpu is in your qoute of mine lol. 7870

the higher i get hte less noticeble the bug is. from 1000 meters up, its not noticible.

@Buchon, no not talkign about hyperthreading

@mazex, thats an hell of a theory, could be just that, its the onyl way to explain this behaviour!

my confusion there if I missed your card, thanks though for pointing it out.. and if the stuttering disappears at a higher altitude, that is exactly what was going on pre Alpha patch.

i think you are missing the point of what im describing

im not getting general stutter.

picture this, my plane is moving softely over the ground, tracers move without any kind of issues, somooth as silk a 60 fps game. but the ground jsut doenst keep up, the groudn itself feels like its refreshing every 0,5 seconds, with small stutering like a 20 fps game. yet the game is still running at 60 fps.


i never had this before the alfa. before the alfa i had smooth as silk everithing at about 40 fps.

now i have th 50% increase, but with this strange effect.

that's what was happening... what monitor/s are you running?



what was your secret??


wow, what is your secret??

What is moved to a separate CPU core is the land geometry generator, the texture handling is done in the GPU by the texture manager.

I have this issue too and its not the CPU trust me, what you are describing is the Hick-Ups that BlackSix listed as known issue.

I´ll not worry by this with that card, I think it will be fixed once the grass and trees optimization is done.

a

This is what I am holding out for! I am praying that once the grass, trees and clouds are optimized then we will have a game. The only thing that worries me is if it is only going to be a matter of days to fix these things like BS stated, then why did they release the pach? Why not just wait if they will bring vast improvements to the FPS?

"grass and trees cause hick-ups. "

indeed. i supposed hick ups would be 2-3 second stops.

mistery solved. thanks Buchon!

They released this for search and crush the CTD issue for once and all before step forward, that's the whole purpose of the Alpha test.

Send your crash files guys ...

That doesn't indicate what monitor you are running though...

and, you did... everyone did. What you describe FPS and stutter/ shudder wise is similar to most other players.
the stuutering/ shudder is more pronounced when the terrain is moving across your screen than at an angle?

Cool then I really am looking forward to the next patch.

my monitor is a 19' from 7 years ago does that really make a difference?

not sure waht you mean by the last part of the post tough.

its easier to spot if i watch downward at a low FOV. but its noticeble all over.

then again. its a know issue after all, a comprimise in the beta release. so this thread no longer serves its porpose.

no, it isn't a "compromise" at all... the low altitude stutter has always been there and known about (FSX had the same situation - oversaturated bus)

I'm sorry, I didn't realise there was a problem for you in indicating which monitor you were running.
Early series LCD's were terrible for shudder and even for later LCD's, a drop in FPS from 60Hz will have stutter/ shuddering occur.

ok. for the last time. i didnt have this issue before.

well im not being rude really. im just not near it at the moment and i cant recall the model. i was actually being straight honest in asking if it really made a difference. And seems like it does.

well, what was your secret??

for the last time. none.

to be fair, im the only one on my squad that has this "ground lag stuttering bug" even now. thats why i came here looking for someone else who had it. none of my mates has it right now.

you can ask all of them the "secret" but there isnt any, some bugs jsut pop on systems and dont pop on others. there have benn people with CTDs with the alfa patch every ten minutes, and some ahvent got a single one.

Still a bit daft to release a patch that was about doubling FPS when you know damn well it's going to stutter on the ground and around clouds that have not been optimized. Setting yourself up for a barrage of complaints when you do things like if you ask me.. Which is why I remain skeptical about the next patch and what it will achieve. I just went and had a go at bomber intercept and my FPS through the clouds were 11 FPS lol. Made me feel like a tortoise with arthritis it was that slow.

Have the same here, no stuttering / freezes over sea, tons of stuttering / freezes over land.
The internal FPS counter stays always over 30 FPS in both situation.
Before this patch was ok, very small stuttering over land and 40 FPS.

I think you may just have contradicted yourself in that post. No stuttering, but everywhere really lol.

i agree with the OP's original post, but its happened for me since day one.

i call it the CLOD shuffle (and hum it to myself along to the tune 'doing the lambeth walk').

580GTX here.

?

I've I? Sorry.

What the part you don't get?

Over the land (landscape)= lots of stuttering.

Over the sea = no stuttering (only made a small test).

Edited: looks like the internal fps counter is not affected by the stuttering / freezes.

Edited: Didn't notice this could be relevant but I also have the "red box on a black background" when the launcher starts.

thank you for reminding me. my 5770, has been upgraded to a 7870. im psoting on this foruns cuz is the only place i have to get info, and utterly report bugs on bugtracker.

honestly i wasnt rude to you, why did you kept coming at me like i did something to you?

oh, and welcome to my ignore list.

I think you answered your own question there

If you turn off trees maybe grass as well this will go away mostly.

Yes it's not nice to get rid of the one feature than gives the ground some life and dimension but they did say there were still issues with trees and grass.

I just did a dogfight above London and I get low FPS but not the ground issues you are describing. Are you using 'original' textures? They are HUGE...

FROM: http://forum.1cpublishing.eu/showthr...554#post308554 (a pre-beta discussion, but still relevant)
He has this monster: i7 3930K @ 5Ghz AC Kryos Silver WB - Asus Rampage IV Extreme - 4way SLI 3GB GTX 580 Aquagrafx WB - 16GB DDR3-2000 - 4 x GTX 360 rads w/ 24 x CM fans & shrouds - 2 x Enermax 1500W PSU - MM Extended Ascension Horizon XL-ATX Case - 2 x Koolance 452x2 Res and 4 x D5 pumps - 3 x 24" Acer H243H LCD Nv Surround
And turns it down to reduce stutter.

hi thanks for the reply.

i would like to make this clear once again, i did not have this issue before the patch.


regarding Path's advice, they refer to an older build of the game, 2 patchs or so ago. so they really dont reflect the reality of the sim anymore.

im going to wait for the final/last beta of the patch. this is a know issue by thre team after all so im not worried anymore.

I'm pretty sure the advice is still relevant, the original textures are still way oversized... Anyway, I hope you get it sorted out.
