177.79 beta driver seems good so far

Recommended Posts

Just downloaded and installed the new beta 177.79. I have to say so far so good. I'm running 8XQ AA with override app and 16x AF set to biliniar in fsx. I dont notice any added stutter and seems to be a little smoother overall. I say give it a try.

I agree. I rarely install beta drivers but decided to try these as I had heard good things about their performance. They work great for me and seem smoother.Jim

What driver were you using prior to this beta? I'm running 175.19 without any real issues.

Ray,I guess you were asking me. I was also running the 175.19 WHQL drivers but the beta's seem a bit better. Should they give me any problem I'll dump them in a second. This is the first time I've used a beta driver for a long, long time. Does it fix any problems in FSX? No. But I believe I'm getting better performance.Best regards,Jim

Hi Jim,Yes, I did direct my question to you. It's very difficult to subjectively assess new drivers. I tend to use a frame rate test to determine if one set of drivers are better than another.Smoothness is very difficult, if not impossible, to assess with any degree of accuracy. The other issue is OS. Those with Vista claimed 175.19 were a lot better than earlier ones but on my XP system they appeared identical to 175.16.Maybe they're better on your Vista 32 than they would be on my XP system?

Ray,I am running XP Pro 32 and actually see a bit of performance increase. I was using the 175.16 and thought they worked well. I feel the 177.79 is noticeably better in smoothness and a few extra frames as well. I tried the 175.19 and couldnt get rid of the stutters no matter what I tried. I have a very modest system and with all the help on here am able to get 3o FPS or higher in alot of areas even while flying my Super80 by Coolsky. (great great bird) The heavy hitting areas do stop me in my tracks but thankfully there are more areas with great performance than areas that are not.Jim W

Hi Jim,Some numbers (before and after) would tell a fuller story. I have updated my XP drivers several times and have yet to see any significant improvements.I lock my system at 30 and it can achieve that 90% of the time. The other 10% is on approach and taxiing around when things get heavy. If others report fps improvements with 32-bit XP and FSX I may dip my toe.Cheers,

I usually fly with my FPS unlimited so what I have noticed is that in areas where I got 25 FPS or higher (I stay away from the big hitters) I am now seeing a 5 fps average increase. That may not make you want to change your current set up if you already are seeing 30 locked 90% of the time but maybe you would see improvements when on approach or taxi. The overall smoothness is with out a doubt much better IMO. I have a 8600 GT Super Clocked edition with DDR3 256mb Ram.

Hi Jim,The increase is encouraging. :-) Unfortunately all my flying is IFR and that inevitably means flying into large airports such as EGLL.With Aerosoft Mega Heathrow my frame rates remains around 10 on approach and even with these new drivers that may only increase by 1 or 2.I flew from Dublin to Nice, Framce today in FSX and flew back using FS9. The return trip (frame rates locked at 50) made the experience a more convincing one than the outbound.I'm considering staying with FS9 for a while. That was my first flight for a couple of months and FS9 did not feel like a prehistoric relic. And with those frame rates is there any need to change anything when frame rates into the FS9 Aerosoft Heathrow remain in the 30s?Cheers,

Jim W,Thanks for the heads up!I installed the new drivers and made my standard test flight and compared average fps.FSX SP2, DX9 mode, Vista 32.Avg fps with 175.19: 62.6Avg fps with 177.79: 62.4My conclusion is that the performance is equal between these two driver versions.Regarding smoothness I can't notice any difference.Ulf BCore2Duo X6800 3.3GHz4GB RAM Corsair XMS2-8500C5BFG 8800GTX, Creative SB X-FiFSX Acc/SP2, Vista 32

Ulf B, Those are some sweet FPS you are getting! What kind of slider settings do you use and get that kind of performance?Thanks for the test results!Jim W

Ulf,Wow! 62 plus FPS! That's almost twice as good as my max FPS with my more powerful system and I have all land and sea traffic turned off (yours is on), no autogen (yours is on), AI set to 40% (yours is off), and all terrain and water settings lower than yours, especially level of detail radius is set to medium). The best I can get is around 38 FPS but it's closer to 30 on average. I don't use tweaks or RivaTuner. You're some tweaker!

Jim,Do you run those 8800GTX cards in SLI? What happens to your fps if you remove one of the cards? I've no experience with SLI but judging from some posts on Vista and FSX, SLI might not be increasing fps as expected.Ulf BCore2Duo X6800 3.3GHz4GB RAM Corsair XMS2-8500C5BFG 8800GTX, Creative SB X-FiFSX Acc/SP2, Vista 32

"Do you run those 8800GTX cards in SLI? What happens to your fps if you remove one of the cards? I've no experience with SLI but judging from some posts on Vista and FSX, SLI might not be increasing fps as expected."Yes, Ulf, you're right. Even Aces said there's no increase or it's so marginal it doesn't really help make FSX go faster or operate better. I've mentioned this in several other posts - I made a major mistake getting dual cards. But I got my system soon after FSX was released and previous versions of FS were GPU intensive and I figured I would be on top of the world with two massive GPU's. But soon after release it was determined FSX was more CPU bound. Okay. So I made my first computer mistake ever. I think several others fell into the CPU/GPU trap so don't feel too bad. If there are any further iterations of FS (and I heard there will be), I will hold off upgrading my system until I know what's happening. I'll let Phil Taylor be the guinea pig...In all fairness to Nvidia (and ATI), the display drivers do make FSX run smoother (or better) (and smoothness is only in the eye of the beholder). I remember when the first display drivers were released for Vista. FSX was stuttering, and graphics were pretty blurry in most places. FSX also crashed fairly fast with the display driver not responding message. Over a year later and several upgrades of the display drivers and my graphics are as clear as I have ever seen them. And, I don't see as much stuttering as I use to. So, things are getting better and better every day. Again, it's all in the eye of the beholder.Now if someone can just fix the display problems with DX10 Preview enabled!Best regards,Jim

Ulf that is nice of you to post screens of your settings like that. Every time one of you fellow FS'ers does that, I always learn a little bit more, because I add it to the storehouse of knowledge that I keep.Interesting that you run mesh complexity of 91. Have you found that there is actually NO difference between 91 and 100, or is there a difference, but it's so minor that it doesn't matter?

I don't focus details like that when I'm flying (it would ruin your FSX experience). It's a coincidence that it's set to 91.I focus on the setting of sliders when they have an clear impact on fps and on the visual appearance of FSX. I also use your and other fellow simmers experience and discoveries (thanks a lot, guys).Ulf B

You know, another thing I noticed. You are running "Trilinear" filtering.I usually run "Aniso"I tried your settings last night, and when I had it set to Trilinear, the distance areas were much less defined. On the other hand, when I set it to Aniso, the distance areas are crisper.Now, I realize with a realistic visibility setting, this isn't much of an issue, but on your hardware, do you notice the same effect?(BTW, I did notice a performance difference between the two filtering settings. Is that your reason for running Trilinear?)RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT

Well ... I gave this beta a try. And I have to say that for me this is the best yet. There is a definite smoothness factor in FS9 and X, and I may have gained a few extra frames. It's a keeper.

Man, I hate to have to say it, but I've had to go back to 169 drivers. All of the 17x drivers cause my computer to hang for 2 or 3 minutes during start up, and have artifacts in FSX. Bummer, I like having all the latest updates.Bob
