Wondering if I should buy the Maddog, but how heavy is the Maddog on the performance vs PMDG 737? 
 

PMDG is running beautifully on my machine. 

The PMDG 737 is much heavier on frames than the Maddog.

The Maddog is the least taxing in performance out of all the releases lately.

FROM MY EXPERIENCE & HARDWARE

Edited May 29, 20224 yr by blueshark747

Out of three new tubes with the pc specs listed in the signature at 4k, the best is the 737. The Maddog is a close second by a couple of frames. Very similar but the PMDG does win it out by like 2-3fps.

The worst is easily the Fenix. Still playable but noticeably worse in fps performance.

Now that you‘ve heard two opposing opinions, I‘ll finish that up with: on my system 737 and Maddog perform equally.

Get PMDG 737 no doubt. Performance aside, the quality of texturing and modeling of PMDG 737 is top notch and cheaper

The OP didn't asked which one to buy, since he said he already has the PMDG 737. He asked if he should get the Maddog as well, but was worried about performances.

I'd said if the PMDG run "beautifully" on his system, I'm sure he won't have any issues with the Maddog as well, their both perform good, and any fps differences are really minor.

I have all of them and havent spent so much time on MSFS before they were released. I dont know why but i found performance to be almost different day by day. Maybe the constant online thing is pushing performance? 

I7-4770K@4,5 HT  GTX1080TI ,32GB RAM.

Best performance on my system

1 PMDG737

2 MADDOGX (-3%)

3 Fenix (-5-10%)

Nope, the Maddog and to a greater extent the Fenix have deeper system modelling than the PMDG aircraft. PMDG aircraft have modelled almost every system, but as a boolean system (= condition is either ON (1) or OFF (0), or something like this), while the other two have simulated the systems themselves, so that different systems can also interact, e.g. on failures. Pretty hard to explain, but anyway those calculations use more CPU power. (That's not the only reason for different performance, of course.)
 

The Maddog just needs some texture and sound work, other than that its up there with Fenix and PMDG as far as simulation, too bad its not flown in the Real Word much anymore due to being a old bird.

Nope? What do you meen by that?

First part of my message is about MSFS itself and the performance on that platform which changes .

Second part is facts about the performance between airliners.

I have both and really not notice anyone worse then the other, but I do like the MD80 since it is 'old school'.

How do they get parameters like voltages, pressures, quantities, etc., out of boolean systems? Unless one has access to the source code, how does one know which systems are more deeply simulated?

Thanks.

Uh yes sorry, I accidentally skipped parts of your post while reading. I thought you were connecting performance of those airliners to the Fenix being "online" (metars, simbrief etc.) and the others not. I need to read better next time...

Yeah, same. It's the perfect blend of old and new. It has an FMS and can follow a flight plan by fixes rather than the pain in the butt that is VOR to VOR navigation, but you still have to manually handle a lot of systems that are automated in the newer birds. Just a fun plane to fly.

Of course the MD80 has the least performance since it is a direct port from P3D.  No great textures or sound to process.  It was a waste of money for me, but you may like low quality textures and sound ....
