P3Dv5.2 HF1 - Embraer E195 Ejets not working with EA etc (Not flyable)

[captzjo]

Hello team,

trying to use the Embraer E195 EJets for p3D v5 and I am unable to fly the aircraft while EA is enabled. As soon as I load my A/C I get a VRAM error. Nothing with any other aircraft. 

Is there a fix for this problem. Hope you guys can help out please. 

I have a GTX1080 with 8GB of vRAM memory

Appreciate any advice/support

Thanks

What level have you got textures set at in the sim? If 4K, I would drop to 2K or even 1K and see if that helps. 

There have been a few efforts to re-size the texture set for various models of the E-jets. Search the forum for these, some of the file sets are available to download and I think the 195 might be among then. This helps because even if the sim is set to a lower texture number, the texture itself still gets read into RAM before being re-mapped. 

For example, sitting in the E170 at ORBX EGHI (which is not the most demanding airport, admittedly) with 2K textures set in the sim and the actual aircraft textures downsized to 2K, I've got 5GB VRAM used with two views open. Sitting in the VC I've seen it as low as 2.5GB. 

At the end of the day, though, a GPU upgrade is really the way to fix this. All the new stuff in P3Dv5 consumes VRAM, modern scenery consumes lots of VRAM, and complex aircraft do too; and while 5.2 has definitely improved the handling of it it's still DX12 which does not hold the programmers hand the way that DX11 did. I know that's easier said than done right now, as buying GPUs is... hard (!), but going to 12GB VRAM would really help you. I know a lot of simmers have gone all the way to the RTX3090 with 24GB VRAM. I think that's slightly overkill now, but in a couple of years, who knows? I just paid way too much for a 3080TI (which is basically the same as a 3090 in performance terms but with 12GB VRAM) and while I'm not happy about how much I spent, I'm happy about the increased stability.

Hello Textures are at 2K. I have the 1080  with max Vram Usage. Not sure if there is something wrong with the aircraft itself or not.

No other aircrafts have this issue.

Sorry, missed the notification for your reply...

Lots of people have reported that the E-jets are very heavy on the VRAM - there are other threads in this forum on that. But I've not seen anyone reporting VRAM-related crashes just loading the aircraft. I use the E170 every day and I don't see that. 

The GTX1080 has 8GB VRAM. That should certainly be enough to load the aircraft. Try setting all the sim settings to minimum apart from the texture settings (leave those at 2K) and see if the same crash occurs. If it does, then I don't think VRAM is actually the problem. If not, then it would seem that VRAM is the problem, but in P3D v5.2 HF1 at 2K, you should not get a VRAM crash at high settings. LM has eliminated most of the crashes.

But to answer the wider question, there is no general problem with the E-jets crashing the sim on load that I am aware of, or that I have experienced.
