Bug-Thread for RC1&2 British Engine Hotfix + SLI/Crossfire test & RC2 release

[Kwiatek]

I made some FM test and found such bugs:

- ALL Spitfires engines except Spifire MK1 (2-stage prop) stop at idle

- Hurricane Mk1 100 Octan engine smokes like the hell at emergency power +12 lbs and mixture in auto reach position (rearward postion) - if mixture is weak position ( forward) smokes stop

- 109 still is too slow ab. 25-30 kph at the deck

- All British fighters are too slow at the deck ab. 20-30 mph ( ex. Spitfire MKII in CLOD reached at 0 at +9lbs 260 mph/418 kph - so speed accurate for IRL Hurricane MK1 at +6lbs but IRL Spitfire MK II reached at +9lbs 290 mph/466 kph - so it is 48 kph difference)

- high alts performacne - above 15 000 ft is just joke - British engines start to shake at little above 20 000 ft, climb rate is heavy reduced above 15 000 ft

- all fighter planes had reduced ( or too weak) rudder effectivness expecially at slow speed with engine power on - not possible to make correct stall turns


For plus is that now Merlin engines don't overheat and damage so quickly so now is possible to keep more accurate engines settings from manuals.

I don't think it's a bug when the engine cuts out with the throttle lever all the way at idle. You need at least half an inch throttle to keep the engine running at a healthy rev with these engines. For not idling too much, there's even the amber warning button (next to the throttle lever) that will have the alarm sound should you throttle back all the way without having flaps and gear down.

The engine won't cut out with the throttle all the way at idle during landing when you're too fast/high but it doesn't like it. Idling too much als causes spark plugs to foul. Shoud this be implemented here (as it occurs in a real world WWII aircraft) then, you will notice that when that happens, you will not have full power until the plugs are clean again (which can be attained by putting high rev on the engine until it purrs nicely again).

I haven't tested the new patches myself yet, but i'm anxious to try the final release.

As a note: I understand the frustration of some forum members at the status CloD, but then again, what they have to deliver for only like 60 bucks... That's almost what you pay for a A2A Spitfire plus accusim. And there you get just a plane, they don't code a whole sim. And they don't even have to include a detailed damage model for the whle airframe. For me it was the best tutorial for the CloD Spit. But it shows about how it should fly in the end. Amazing what they did with the limited possibilities of FSX.
CloD can really shine one day. It could beat what's out there. However I think we all (or most of us, including devs) underestimated what it takes to live up to a dream... But in time... maybe?

So long,
Zach

The alarm horn is to warn the pilot from a landing attempt without gear down. The following paragraphs are from the Merlin II and III engine manual (A.P. 1590 B, Vol. I). In short: The engine does not stop when throttle is brought to the idle position, in fact a "Slow Running Cut-Out" device was introduced to allow stopping the engine without the need to switch off the fuel (because this method is a bit complicated).

Honestly I don't care about that as long as the AI is able to keep the engine running on the ground ... which is not the case at the moment.

Hi friends... a one question...

aer SLI working now with last patch?????

I have 2 Nvidia GTX 275 and not working SLI...

Any rule to install or make to run SLI???

thanks

I dont think this patch was to add SLI performance boost, just to stop crashes related to having SLI enabled...

The problem does not come from the Hurri model. It turns well and realistically

It's more the Energy free Spit turns that makes you feel like the hurri is sluglish. The 109 is also over optimistic in the turn.

IMOHO a patch shld temper this and not modify the hurri.

C'mon guys the SPit we hve here outurn a G50!

[RickRuski]

After trying most of the things I could think of, plus others that have been suggested I've abandoned the latest patch and hot fix. It is a major step back in performance for me so I've re-installed beta 18956.

Result: - Better fps, less load on cards, lower temp on cards and most of all far less stutters.
Also I don't have the double reticle at load any more.

Will leave any other patches and hot fixes etc until Nvidia does their thing with Sli driver profile, then will try again.

As said, thank you for the info. Didn't know that source yet. I will have to check that. Makes perfect sense.

Cheers,
Zach

.
The Spitfire MKIa 100octane has a big problem when it reach 20.000 fts I tried every engine control setting but nothing change it. 19.900 all OK 20.000 all bad and strange the Spitfire MKI does not have this problem at all. Now I am going to try the Spitfire MKII.

[Kwiatek]

Spit MK II has aslo engine problems with 20 000 ft. High alts FM is actually joke in all planes. In steady climb i could reach only 7400m in 109. British fighters are even worse and get engine problems above 20 000 ft.
