Funny, I had the EXACT same thing you are describing when I overclocked my Video card.. I had to downclock it just a little bit.I no doubt think BP=0 stresses the card even further, so, overclocking it wont help, are you, by any chance running very high AA and AF settings?

Hm, I don't OC the card at all: it's running stock. AA is 4xS (one notch lower than NickN's suggestion), AF is 16 but that's almost a standard setting nowadays... As I said, I even have some setting in nHancer at performance instead of quality. Come to think of it: you don't use nHancer, right? Maybe that's got something to do with it. Although enough people who have succes with BP at 0 do use nHancer. Another simple solution might be that I have to turn autogen down to Dense... but that's not really an option when it runs okay at Extremely dense and BP at 500000.You know what, I'll see what happens if I use nVidia's control panel instead of nHancer. I'm just can't get enough of that sweet tweaking. ;)

I have seen memory errors cause artifacts, if you are pushing your timings or overclocking a little too hard, or your RAM voltage is a little to low any of theses could be the source of the aritifacts. I do however, feel that this tweak stresses an FSX system harder than anything previously experienced and that drivers, timings, fsx.cfg settings etc.. are even more critical for one to have success with it. So many variables.Regards,Bob

in fact, it does... if you monitor Video card GPU/memory and temps you'll see this yourself.. CPU usage is exactly the same, it is just the GPU working harder, why?

That is interesting. I have overclocked the daylights out of my EVGA 275GTX with 1792MB taking the core clock up from 633MHZ to 721MHZ, shader clock to 1600, and memory to 1206. This is all within do-able stable stats according to to this Guru3d review.I lowered my Nhancer setting as J Van E had suggested in a different thread without noticing any deterioration of quality. I really have good performance and quality, but want more and more and more... :( Stephen

Stephen, people who overclock usually make statements such as: Prime ran 24 hours rock stable, but my games crashes to desktop so I know it is not my overclock.The above statement only shows his/her lack of knowledge of how hardware works. CAS latency, PSU, load shed, USB, Video Card, voltages under REAL WORLD scenarios are very different than a simply benchmark test.. not even Intel Burner can give you an indication of an stable overclock. For Video Cards, is the same thing... if you want to stress your machine run prime or Intel Burner but at the same time run the GPU stress tool Funmark and also copy a HUGE file over to an external USB drive running HiSpeed mode USB 2.0.. during this period, try to open and close windows, check the temps and specially see the voltages and any fluctuations. I'm not against overclocking... I run at 4.2 on air using an old C0 i920.. however, my VIDEO card is VERY VERY sensitive to overclocking, because I'm Pretty sure it needs more juice.. however, you can't give more voltage to a GTX285 without an external mod.My point is: check how your card behaves running at stock clocks to see *IF* this plays a factor on what you experience running BP=0

Nick, I didn't know that you recommended no BP entry for i7 system. Is this new?

Win XP SP3 32bit here...... Latest Nvidia drivers.... 196.21 ..........BP set to 0Had a positive response from FSX... Flights very smooth, display very crispDan

Win 7 64 bit here...Drivers: 196.34BP: 80000000Smooth as silk!BTW: We had "The Holy Grail" - ******* told us!When will the Virgin Mary show up? :(

I also tried BP=0. I usually run BP=300.000.000 with TBM= 70 without stutters or texture corruption. I noticed that BP=0 increased my FPS somewhat and the flight was very smooth, but after 30 minutes inflight i got corruption and had to reboot my computer. Also tried BP=50.000.000 and 20.480.000, no corruption but lots of stutters (replay is a slideshow). I'm, going to try BP=0 with TBM=60 and see what happens. This is with latest Nvidia driver, nHancer, AA 8xS and AF 16x. Autogen very dense and water 1 notch before max.Thanks for posting this, bojote. It may well be a valid tweak.

Hi *******,You make another good point that I agree with. I ran Furmark and stressed the GPU to the max for several hours, as well as the OCCT gpu stress test. The card was clocked higher, if I remember right, to something like 743mhz, but had to be lowered and retested after I noticed irregularities. Bench testing showed that my power suppy was insufficient so it was swapped out for the single rail 12V design I now have. GPU tempertures remain 55-60C + or - under load. The flashing with 0 BP might indeed be caused by the overclock, but I can't see how that would be theoretically, do you? But even if so, perhaps the benefits of the OC far outweigh any likely benefits otherwise. Thinking...thinking...please wait...thinking...Stephen

.... and born Jan 01, 2000.

Man, I can't stand that loading screen anymore... :( I've done numerous tests, again, with BP at 0 but now with nHancer removed from my system. I set up the GTX285 with the nVidia control panel, focusing on performance instead of quality. FSX still looks great, but FSAA is on the edge of being okay... But that's mainly above cities, and since I mainly fly above trees, that's no problem. Anyway, artifacts are a lot less horrible. They don't screw everything up anymore and they also don't stick. However, I do see flashing things every now and while I don't see things with BP at 500000... But... all is not lost, because my new 'low' none-nHancer settings really boosted my fps above trees! In my test-flight I now sometimes get 40 at places where I used to get 30! That's a 33% jump! However, above (Extremely dense) cities (where I have another testflight saved) fps is only up a little and it's not really smooth. But it was never really smooth there, so...Right now I have to decide what to do: keep a higher fps at the cost of quality or not... I have done any long flights yet, so I will test and see what happens then. But that's getting OT, really, because I have to come to the conclusion that BP at 0 is not for me... Still, all this tweaking led to progress anyway, so... all is good! ;)

Man, I think you must suffer from the contagious continuous tweak disease too. :( Stephen

Well... theoritically, flashes (or tearing) is usually problems with VSYNC, Triple buffering and/or stressing of the video card. I assume you have VSYNC on as well as triple buffering correct? how about limit your frames?, have you tried something like 25 with a TBM of 60-90?as for 'overclocking' the GPU and seeing any benefits in FSX.. well, I'm not sure I'd agree, and you can easily this see for yourself.. just notice CPU usage AND GPU usage while using FSX.... CPU is always maxed out, while the GPU seems to running with a VERY light load.. HOWEVER.. in your specific case, CORE Mhz for the Video card would NOT be my concern... I would be looking at the shader clock AND memory clock, they are VERY sensitive to FSX, specially because FSX uses huge amounts of VRAM, and also makes use of shaders extensively.

LOL Yes, I do. Every evening I think 'Now I am going to FLY' and I always end up tweaking.However, not all is pleasant: just now I wanted to compare various FSAA settings once more, but now my system is STUCK in FSAA 2x... I even reinstalled nHancer to check 4xS and so on, but whatever I do, FSAA won't change and is stuck... Even if I keep in using this setting in FSX, I don't like this... I want to be able to try different things too! Bummer...EDIT:Ah, never mind. I turned on the ingame FSAA and all looks good. I also pressed Shift-Z and without those nasty little red letters at the top left of my screen, it even looks better!All in all I am a happy man because all the tweaking and testing from the last week brought me from smooth Dense forests to smooth Extremely dense forests: the difference is amazing, awesome and worth all the trouble. And all that for free! :( I am ready for PNW now.And tomorrow I will just FLY. Promise. Honest. I won't tweak. Really. Believe me. I won't. I just won't. I refuse to tweak anymore. I will only fly. FLY!Yeah... right... :(
