Still here... *no mods* Syria F18 free flight mission: - Flown for 10 secs - ESC - Changed SSAA from 1.5 to OFF (glitching as per patch notes) - Reloaded same mission (from main menu, not "fly again" obv) - Crash NB: I updated to the latest OB then ran a slow repair before launching DCS. FXO & Metashaders 2 deleted. New NVIDIA drivers 466.67. full screen off & other settings as per Flappie instructions log attached dcs.log dcs.log.old dcs.log-20210602-172110.zip debrief.log

I am experiencing this crash since the start of this 3d and I have a 3090 + 10700k (full specs in my signature) I don't think it's hardware related

Thanks! I'll give it go no idea why it is set at <16gb.. it's a new pc build (last December) with a fresh DCS install and haven't changed any component since except my gpu

here they are. *edit* re-upload (it was messy before). -923 & -802 had a large track file in them, had to delete it due size constrain upload dcs.log-20210419-103802.zip dcs.log-20210415-151923.zip dcs.log-20210418-090242.zip dcs.log-20210429-185348.zip dcs.log-20210429-180418.zip dcs.log-20210428-195226.zip dcs.log-20210427-221736.zip dcs.log

FYI 466.27 is known to give a performance hit on some builds. *edit* my bad I meant 466.11, haven't tried the .27 which was released on the 29/4. I had 466.11 until yesterday and DCS was crashing constantly on second load of the same mission with those drivers. Rolled back to 461.72 and game is still crashing. I did get some of the performance back though (not quite at the same level of 2.5.6 but a small improvement anyway). Link here to the other 3d: MASSIVE fps drop after update to 2.7 What I found out recently is that reducing my preload setting to 100000 and deleting all the custom NVIDIA control panel settings for DCS seems to have reduced the frequency of the crashes. Now I can sometimes load the second time the same mission without issues, however it still crashes every now and again. The mission I am testing this with is a custom F18C mission in Syria with some AI and many static units. Maybe RAM usage is linked somehow to the crash? This mission is quite RAM intensive (as is Syria by default). Reducing the preload could have an effect on RAM usage and therefore reducing the frequency of the crashes? I am sending the crash log with the prompt every time it happens. @Flappie if you need it I can also post them here

Quick update on the FPS issue on my system Following the below actions which I had done before: - Windows updated - Clean Saved Games folder - Deleted temp folder - Slow repair Today I: - Rolled back to NVIDIA drivers 461.72 (used DDU for clean install) - Removed all custom NVIDIA control panel settings for DCS Gained some of the FPS back on top of the small gain I had before. Again not quite the same performance as 2.5.6 but a small improvement nevertheless. The biggest difference with rolling back the drivers is that I am not experiencing anymore some "dips" I had with the latest drivers (466.11). Occasionally I would experience a drop from 60ish to 30 and then immediately back to 60 together with a GPU % utilization drop from 98%+ down to 75% and then back up to 98%+. This does not happen anymore with the "old" 461.72 drivers. The behaviour above is (was) clear on a mission I am playing with the F18C in Syria when taxing around Incirlik AB. (custom mission, some of AI and many assets parked around) just my 2c

Nice one! I'll try to roll back on 461.72 to see if I can also have some improvements. Did you notice any changes when playing non-VR?

So I did the following procedure in the attempt of fixing the crashing issue on launching the second mission and also to see if I could get some performance back: - updated windows - reapplied NVIDIA control panel settings for DCS - renamed DCS saved games folder - deleted the Drive:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\terrains\*Terrain name*\misc\metacache\dcs folder (repetead this for all the terrains I own) - deleted the Drive:\Users\*username*\AppData\Local\Temp\DCS.openbeta folder - performed a DCS repair - check all files (slow) - launched the game and re-applied all settigns as I had before with 2.5.6 - copied the Saved Games\config\input folder for my custom bindings - copied the logbook.lua file from the backup folder - copied the autoexec.cfg custom file from the backup folder On the same Syria F18C free flight mission I saw a minor improvement of about <10fps compared to what I was getting when I first installed 2.7 Not at the same level or better than 2.5.6 (at least for my build) but is a step forward. For info I am getting an average of 75fps with dips around 58 and spikes to the 90s. The fps drops happens when I look sideways over the aicraft wings I should add that the above procedure seems to have fixed the game crash when launching a second flight link *edit* it didn't Forgot to mention: I am testing all of the above in 2D mode with my 34' screen (3440x1440) @ max settings except SSLR and SSAO. Haven't touched VR yet Have to say that despite the loss of fps it does indeed run very smoothly and it looks stunning, especially on Syria at maxed-out settings

an update on my end. I did the following procedure: - renamed DCS saved games folder - deleted the Drive:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\terrains\*Terrain name*\misc\metacache\dcs folder (repetead this for all the terrains I own) - deleted the Drive:\Users\*username*\AppData\Local\Temp\DCS.openbeta folder - performed a DCS repair - check all files (slow) - launched the game and re-applied all settigns as I had before with 2.5.6 - copied the Saved Games\config\input folder for my custom bindings - copied the logbook.lua file from the backup folder - copied the autoexec.cfg custom file from the backup folder so far no crashes on launching any mission multiple times. I have tested only the preloaded mission that comes with each module (e.g. free flight) in all the terrains I have. I did a combinations of A10C II, F16, FA18, FC3 on caucasus, PG and Syria on the same game session. I'll update here in case I encounter any further crashing *update* loaded for the second time a custom mission (A10C II BFT Campaign mission 2) and it crashed again log attached dcs.20210415-151923.log dcs.20210415-151923.crash dcs.20210415-151923.dmp

I'll try to rollback my driver to that build and I'll report back

@Flappie I think XPACT mentioned that even deleting options.lua seems not to be working

Interesting. Which nvidia drivers are you using? I updated mine today just before DCS

Same here, noticeable with a 3090. F-18C Free flight in Syria (with new clouds) I get around 60-70fps while before it was around 90 (all settings maxed out, res is 1440p widescreen) I noticed that trees shadows now render with a "soft edge" when flying closer to them as opposed to before where they would stay with a "sharp edge". You can clearly see the transition from the "low res shadow" to the "high res shadow" when approaching the trees. Didn't have much time to test today but I haven't changed my settings from what I had in 2.5.6 to see which one in particular has this "feature" BTW 2.7 with new clouds + Syria looks amazing

Same here, loading any second mission will cause the game to crash

Great tip! Thanks for that, I'll try this out

Thank you @Rudel_chw, I didn't know it wasn't implemented yet. That's a bummer, I hope they'll add the support soon. guess I'll have to use them via my Saved Games folder until then

I should add that if I copy your files in the /Saved Games/DCS OpenBeta/Kneeboard folder it works just fine (both .png and .jpg) however I'm looking to have those charts visible only when you are flying specifically on Syria map, hence my question regarding the directory for Syria map

thank you @shu77 for your amazing work!! I managed to install your PG charts with no issues but I'm having a problem with the Syria charts. I installed them into DCS World OpenBeta/Mods/terrains/Syria/Kneeboard but once in game they don't show up when I use the kneeboard. I tried to change the format to .jpg but same result. Does Syria Map have a different folder where you should install the map-specific kneeboard images? Thanks

Great stuff!!

As per title, only from threshold RW29R until approximately halfway the other runways look fine Pics attached Thanks

delete the folders then run a repair. Shaders will recompile once loading the game

Here's the path: Drive:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\terrains\*Terrain name*\misc\metacache\ delete/rename the "dcs" folder. Repeat for each terrain module you own Hope this helps

hi Aernov, Old shaders in the "fxo" and "metashaders2" folders are known to cause stuttering, frame loss and texture corruption (e.g. FLIR view broken, over-exposed). It's a good habit to delete these folders once in a while, especially after a game update/driver update or if you've experienced any anomalies in game. The first time you'll reload a mission or flight it will take longer as it needs to recompile all the shaders, but after the first load it will be back to normal. There are also other folders where the map cache/shaders are stored which you can delete if you experience any weird glitches. Can't remember the location right know but I'll update the post later *edit* Drive:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\terrains\*Terrain name*\misc\metacache\ delete/rename the "dcs" folder. Repeat for each terrain module you own

I think what Taz meant is that when you load more units you are indeed increasing the VRAM usage, but you're asking for more units to be present to make the mission more interesting/alive/more obj/etc ( = feature ). In the case of 32 bit normal maps you are increasing the VRAM usage but with no benefit gained from it compared to the 8 bit, only with a disadvantage of losing available VRAM

Pretty sure is normal behavior due doppler effect. You should select a target offset to either side or maneuver the aircraft to have the target not directly in front of you. IIRC wags mentions this on one of the introduction videos about the ground radar
