Not if you're using 1080 or 1440, certainly in 4k an 11GB card is the minimum for TS=10. My 4k screen uses 3.5GB with ORBX and stock planes at default TS in OZv2 going to TS=10 pushes it to around 6-6.5GB Vram. (HF1 installed) I have only added low overhead aircraft so far (like the venerable TWIN OTTER) and that with ORBX certainly makes the 1080Ti have some hesitations over Sydney but the 2080Ti breezes it. Have never seen an OOM in V4 or v5 to date - luck of the draw there i guess, so I can only suggest more tuning of the settings. If you're crashing out to blue screens like the bad old days I suggest using Bluescreenview which logs the BS crashes in a form you can access and it "may/might" give a clue.

That is one heck of a "maybe".

Clean installs and DDU are de rigeur for me and I also have not used an ATC window so take my comment as info only. I have mentioned this before elsewhere (apologies to those who find it repetitive) but for those who missed it - In my case I saw this problem early in V4 and several times in V5 until I remembered the v4 solution to turn of MSI afterburner (and RTSS) the problem goes away instantly for me. I run MSI full time to OC either a 1080TI or a 2080Ti and if I forget to turn it off v5 will crash with the error message almost every time a make a change at the v5 menu or make a scene change in the air. I was going to verify with some older cards but they are not DX12 compliant. PCs and flight sims are an ongoing challenge - but that is part of the fascination (frustration?).

Why do you find it annoying (and confusing) to select 30fps on your GPU software and 30Hz on your monitor software? I would like to know?

Don't agree with this comment at all. Most of the vids I look at were recorded in 4K, something we could only dream about in FSX whilst recovering from the latest OOM crash and the pathetic 3.4GB ram limit. 4K texture load for me loads quite well sure there is a delay but that occurs in any software that changes on screen reference points nowhere near as slow for me as it used to be.

My past experience suggests that THTGo works well with plenty of other programs alongside P3D. I agree however the modern GPUs have largely made it redundant (for those who can afford a modern GPU). I am also guessing the OP has fixed his problem. Cheers

Pieter you need to give some more details. I haven't used my Matrox in must be all of 5 or 6 years since we have had GPUs that didn't need them.Not getting a key clash somewhere? My biggest problems with the Mth2Go was always drivers even in windows 7 I did get it running fine eventually. Their latest driver for the digital version (W10) I think goes back to 2016 so may have some compatibility issues there, with it and DX12. Hopefully somebody with v5 has got it driving 3 screens in W10 and will chime in.

Probably stating the obvious to you - Have you checked whether the card had a manufacturer bios/firmware update during its life? Not using it, but I know for example my 1080Ti had 2 bios updates in mid 2019 - 18 months after card release and according to Gigabyte mostly focussed on DX12 improvements though no detailed info on exactly what was improved. ps: in my experience GPU bios firmware updates are more risky than Mobo updates I say that because in 30 years of playing with my own builds I guess I have bios updated over 100 times only 2 failures - 2 bricked GPUs some years back now, not one mobo (looks around room for a large piece of wood to touch).

I believe the short answer is no to your symbolic shortcut. The migration as outlined by Ed Correia on their forum is dead simple and works. I am running V4 and V5 ORBX alongside one another as per his instructions . HOWEVER I took careful note of his instructions. I have left all the incompatible packs in v4. I installed the V5 ORBX files as per Ed's instructions (using the manual install option) and then added each scenery pack I wanted through central and verified that file. ORBX does not download it again. Once I had a specific scenery added (eg TE GB) in v5 I deleted it from V4 to save space. Should I want to use a v5 scenery back in v4 I reverse the procedure and thru Central I use the manual install option for v4 and then verify the file again. For True Earth GB this has taken me about 4-5 minutes when I have done it each way. If you want both v4 and V5 ORBX running side by side you have to use their method to get the Global Base, Libraries, Object flow installed for the two instances ( I think that is the minimum). The scenery packs can be moved backwards and forwards as long as you do it thru Central and re verify them each time you do a manual install. Its working for me however with all things to do with flight sims and computers - don't miss a step or you end up at the bottom of the well. I hope my rambling makes sense.

I am running the A2A Skylane and it certainly slows things down compared to default AC but I haven't had the DX12 disconnect error message whilst using it. Did you turn off/rename the windshield.dll in gauges folder as they recommend?

I have answered this elsewhere (P3D forums) - I am willing to bet you are running MSI Afterburner/RTSS (I think it is RTSS). Had the same problem with both 1080Ti and 2080Ti. Turned them off problem gone. Try it?

No problems with my 1080Ti but then again I NEVER use AA on either my 4k or 2kscreens. The night lighting looks great flying over the ORBX Gold Coast with the A2A Skylane. AA is totally unnecessary on 4k imo and kills smoothness which is the opposite of what I am seeking.

Did you follow the instructions? Have to move to beta "fastlane" and central will then update and recognise v5. All in the link I posted above.

That is only necessary if you are going to run both versions of P3D for a period of time. I have changed the ORBX scenery library folder NAME (P3Dv5) back and forth (P3Dv4) twice tonight switching between them and the sim I was flying (to test) without issue. Just open ORBX Central and point it to the P3D version you want to run next. My library drive is an NVME drive so I didn't want 2 folders 215GBS in size with the exact same stuff in both side by side. In my case I checked every ORBX add on I own against the 230 strong ORBX compatibility list and came up trumps. If you do strike one (or more) move them to a folder and name it what you like and shift them back into the library folder if you need to switch back from V5 to V4 after you have renamed the scenery library folder from v5 to v4 using the ORBX naming. Working for me. Their process is straightforward and the single folder naming is the only step I deviated from their instructions. I hope I have made sense here getting late and its been a long day in the lock - up. Been running v5 since 11am NSW time and very happy so far money well spent for the performance gain I have seen.

Short answer no (IMO). I have been through a 28" then a 32" and last (best) a 43" 4K monitor. The smaller ones are terrible for reading the text in normal windows programs (and P3D) because many do NOT scale properly. Simbol is spot on with AA its not required at 4k even at 43" as the pixel density is small high enough the jagged edges we see in cockpit window frames etc at smaller res disappear at 4K. 2k (2560x1440) would be ideal at 32" 43" I sit 36-40" away with a 28" 2K in portrait mode to the right of it. Vram is not a problem yet with the 1080Ti and the smoothness with ORBX Oz v2 is glorious compared to yesterday's v4.

ORBX has a very simple to follow migration process on their forum. https://orbxsystems.com/forum/topic/190948-installing-orbx-products-in-prepar3d-v5/ I have v5 on my D drive and ORBX Central points to its Library in my F drive so the answer is NO on my system at least.

Been running v5 now for 3 hrs on the 1080TI (not the 2080Ti) because I wanted to compare it to my v4 setup which I ran for a long time with the 1080TI so I now its nuances. At 4K with most slider setting 3/4 right and texture at 60cm on both v4 and V5 I have gone from 30FPS steady (I unlocked it but that is where the the 7900X performed with the 1080Ti and the 4k Monitor) switching to V5 ( I am mostly interested in scenery in my part of the world) I have been flying over Sydney at dusk and letting it get really dark to see the lighting come on. Only in the Raptor to keep the AC out of the equation. RTSS and Hardware info both report V4- 2.6GBS vram being used FPS unlocked steady 31.5 FPS whilst low flying and rotating over the city and airport (YSSY) V5 -2.9GBS Vram being used FPS unlocked steady 47FPS (as above) Lighting, clouds way better. default Sydney airport and city is better visually that v4 I want to test soon as possible with ORBX OZ v2 but I have to say I am very impressed with the improvement in the base package. The add on packages should be able to build on that? The water (with cloud shadows ) looks way better than v4. I don't see any issues with VRam and the performance (apples to apples) is way better. From my perspective the next question is how good are the developers at keeping their add on software performance efficient Back to flying, to test everything maxed out because I am happy so far. Joy I have heaps to do whilst I am locked up.

Your spot on OzWhitey = "they" advertise the 14th when correctly if it is 0800UTC that means for most of the populated world it is actually the 15th release date. A company with LM's background could do something radical and state the release time in UTC and not Fluorida time. LOL I am reminded of that great saying we use for the doomsday preppers where we live here on top of the world ie: Don't worry guys if the world ends today, because its already tomorrow in Australia. Keep punching that refresh button you guys.

Straw polls are notoriously unreliable (largely because they typically are single person polls based on opinions) I am reminded of similar straw polls about 18 months ago that indicated flight simmers would never buy the 2080Ti because it was extortionately priced. the beat goes on well said and I suspect you are voicing the opinion of the silent majority lurking here. just my opinion of course.

"otherwise 4.5 is so good I'm happy to wait til 2020 matures in terms of ample 3rd party content, fully debugged." An interesting conclusion and decision. One could just as easily wait and witness the improvements in P3D v5 which will undoubtedly happen in parallel. Making such a decision now before either product is even released based on 3rd person videos is your choice and well based given you claim you can produce better visual flights with 4.5 now. I also will wait for real life FS2020 performance (on the internet) reports because I have a small fortune invested in P3D (stopped investing in parallel in another sim because of its poor support of the southern hemisphere - I digress). I am more than happy with the scenery quality and performance from ORBX at 4k in v4.5 and the flight modelling, the outcome as of now for me is something like FS2020 needs to do something magical at a cheap price for me to even consider starting over. About the only thing that would catch my eye(s) is proper VR performance at 4K (with 120 FOV minimum) with no fly screens and including proper integration of all controls of my chosen AC into the VR experience. As I said I will wait but at my age I doubt I will see it.

Thanks Steve that explains it - I need to do some research now.

Frankly this just supports my statement earlier. One tunes their machine (regardless of spec) and the software to derive the best performance available in that configuration - people do it all the time here and elsewhere. Does not matter if it is an old laptop or a high end desktop the tuning principle is the same and has been espoused by hardware and software manufactures alike.

That is helpful Steve but you have me puzzled. I have watched Rob's vids fairly closely since the release of the 2080Ti and mine handles 1x 4k screen ok on the 7900X (with the 2k screen doing the addons) I have texture set at 9 but if I try 10 the Vram tops out and then the world collapses (figuratively). In Rob's recent vid the Titan was hitting 18GBs of Vram at times and regularly at 12-13. That's what triggered my comment. I have tried both the 2080Ti and a really good 1080Ti on the 7900X and the Ryzen 3900 rigs with the same outcome (which is always going to happen if the settings use more Vram than you available). Are you referring to Ram when you list 31.9GB shared? NVlink allows faster transfer than PCIE as I recall but with full use of Vram on both cards that would be 22GBs or did I miss something?

You are absolutely correct of course, the other problem a friend of mine found was the VRAM limitation. He has 2x2080Ti in SLI he still couldn't ramp the textures up with 4k because of the 11GB limit though they ran beautifully otherwise; the 11GB was just another handbrake on his system. Now 24GB in a couple of Titans would be nice in an Ultimate rig. Again as you succinctly put it ... you pays yours money. Rumour has it the top nV 3000 model (non Titan) will have 16GBs we shall see.

Only if you don't take the trouble to tune your PC set up properly which means Gsync is unnecessary imo. Untold threads in AVSim about setting up and testing your your PC and flight sim software to negate such issues. Ray I agree with your comment about high res vs widescreen. Found 4K (with TiR) much better value imo for its vertical real estate esp TO and Landing. If I could afford the ultimate rig it would have 3x4K screens in portrait mode. (Given up on ever getting decent res and fov in VR coz I'm too old). "maintain separation - stay safe"
