Thanks to the devs, 2.5.5 is apparently much more smooth

I've noticed that the performance doesn't sink anymore for me especially in multiplayer and I've stopped having FPS drops even in high object count scenes after upgrading to 2.5.5. The VR crowd (and not only them) are reporting similar increase in FPS https://forums.eagle.ru/showthread.php?t=242449

It hit me especially hard in MP, and I've been starting to think about upgrading to GTX 2070+ to get like 8GB VRAM . I don't know which of the below fixes contributed to such (dramatic for me) improvement:

- new trees?

- memory leak (RAM or VRAM?)?

- MP code/protcol change?

... but "THANK YOU, ED" :) If you ED devs could explain what they did even in the most advanced IT jargon it would be even more awesome :)

Specs: i5-7600K 4.2GHz/GTX970/16GB RAM/non-VR/SSD - minimum 50-60fps everywhere in MP, in SP often > 110fps. Previously I was having freezes/microsutters down to single-digit FPS...

Interesting, we have the same amount of RAM, you have a better cpu than mine (i5 7600k vs Ryzen5 2400g) but i have a better graphics card (gtx970 vs gtx1060 6gb), yet i am no way near minimum 50-60fps online, more like 25-50max. To jest dziwne, prawda? :)

Yesterday i felt slightly better performances on some servers and worse on others like GAW for some reasons. Not sure if it is related to the update but it is good to know that this update may have improved things online.

My load times seemed improved. Anyone else think that?

My load times increased dramatically for me. Especially on first startup into the menu. It's just a much better smoother overall experience so far.

Faster here too, especially noticeable with the Tomcat. Id say easily twice as fast as before.

- When already in the mission, jumping into a plane (where you have multiple to choose from), the way it loads in, building shaders etc. Much faster in 2.5.5.

Agreed, I'm really looking forward to the additional VR optimizations that are coming. This was already a nice performance increase, it would be awesome to be as smooth as 2D play.

Was better all round. There are a lot of changes. The netcode moved to LEDBAT. We still managed to break it on our servers with a very high unit count and moving units. VR FPS is quite reasonable, the new swaying with the wind trees look better IMO, there's some under the hood changes regarding AI and wind that hit us hard. Still going through scripting looking for issues though, it's early days.

Something has definitely improved indeed. My VR loading times had increased, and my general performance has gotten better as well. I accidentally left terrain shadows to "Default", which normally murders my system in VR, yet flying at treetop level in the Anton I didn't notice any performance dip.

Non-VR here but I am seeing a performance increase as well...about 20 FPS on average. Thank you ED!!!

I like the new trees , and find 2.5.5 smoother as well . Nice !

+1 on the improvement in the 2.5.5. Version. I would normally get an fps of 50-65 before now but I am getting 80-85 now on 2d screen.

I haven't seen much on the VR side as many variables are at play here. From steam vr to dcs PD settings.

Yet to see new trees effect. Would look out for those.

Good job ED.

Unfortunately, in the Caucasus map at least, the trees aren't exactly 'new', they've been a bit downgraded actually:

As to the movement in the wind effect of the trees...that's been around for a year or more...and is very cool. :-)

Nineline has stated that they're looking into the new tree tweak in the Caucasus region. They looked really good (better some would say) prior to this 2.5.5 update.

VR user here and i noticed improvements in performance too. Noticeable smoother.

Best regards,

New trees look fine to me....considering I only ever see them at speed greater than 100kts.

I recommend cleaning up the driver's and DCS's shader cache after such a big update which touches graphics, to avoid glitches.

I am not sure which did it, dcs 2.5.5 version or my deleting fxo and metashader2 folders, never got a 112fps before since playing dcs.

In old dcs open beta version, 50-65fps was my regular marks. After updating to 2.5.5patch fps went to 80-90 range.

Now I am getting into the 112fps mark.

I want to believe the 2.5.5 patch did it.

Amazing

I'm also very grateful that I can now set the onscreen text size to a readable size.:thumbup:

Just praying for a means to control the position of kneepads and control indicators without resorting to editing luas some day.

Initially posted to the VR performance improvement thread .. but fits here better.

Title.

 

Was the 50% increase an exaggeration?

 

Depends on the context, I didn't happen to focus on VR-specific stuff, but a small and easy to fix thing in code can mean huge things in practice, if any of you are following Dolphin-emu progress reports such cases are documented time and time again ... optimization is a big deal.

 

About the impact of LABELS: Stable 2.5.4 (I'm Stable-only these days)

 

(is each of the labels it's separate draw call?)

 

Those could be draw call (CPU) related, something that might have been improved too even without the need of Vulkan API.

 

Same thing for the trees. The engine may be processing multiple trees more efficiently.

 

 

 

As in this example below, on the one hand it's not only about the API, if an implementation (code) of the graphics engine lacks optimizations it doesn't help if a cool new API is used. DCS may had some of those improvements in 2.5.5

 

However on the other hand, you can see how massive the improvement can be when API features fundamentally better capabilities, not only does each draw calls cost much less on Vulkan API, it has the features to do things in one draw call that previous APIs cannot, so to answer the question, rumors of +50% increases MAY NOT BE SO FAR FETCHED. And the bigger question is, if +50% with just existing implementation improvements, what about the improvements with the new API .... so there you go :)

Which map?

I need to do some testing, but it appears that my FPS is actually slightly lower with this latest update, Caucasus in particular. 2.5.4 ran beautifully for me in comparison. I play in 4K.

Thanks, BJM.

I flew for first time since update and I noticed right away my VR experience was better. Great update!

Overall it seems clearer to me. The ground is better, the frames are smoother. During tanking you can see very nicely and I'm pretty sure the tanker was bobbing up and down more noticeably. Nice update.

Overall it seems clearer to me. The ground is better

maybe they added more polygons, more textures, or more sharpening.

Seems smoother here too. VR, O+. Thanks for the work...crossing fingers the VR improvements go even further. I'd rather give ED my money (for the next module, or two) than nVidia or AMD + Intel + Samsung, etc..for a faster computer.
