Fishy explosions are FPS Killer?

Interesting, I’ve been running at 7 since 4.32
I could save some frames if that is really that high. I’d be curious what 7 actually equals in x AA
Yes in-fact, I’m running with 7 myself since I have GTX-780 card, but only because it can carry it NP… I know that on my system the difference between 7 and 3-4 is HARDLY noticeable but the performance hit is also not so serious so I just don’t care to keep it. If I had any performance concerns, lowering quality would be the first thing I would have tried.

Okay gents, after a VERY quick check i can say: no fps difference between 8x AA forced in Crimson application and BMS setting Multisampling Quality 4.

And picture quality? Don’t know for sure but I find the internal BMS settings a little less jaggie, but it can be just my imagination. BTW, I say this with experience from both vendors, before the current GTX-780 I had a R9 280X.

@ I-hawk lol on the video… But still they try (think) to fight it…

As said, just a VERY quick check. I have to made screenshots to compare the two settings properly.
Just a small addendum of the test setup: R9 390 with 8GB, tripple monitor setup, AGM-65 CAVOK trainings te with TGP and WPN page aktivated.

It does say in the manual that diver AA usually has better performance. I did some testing and I found that the AA makes almost no difference to the FPS with explosions. I can turn everything off and it still lags when many bombs are exploding. I even tried reduced particle systems, no transparency AA. Next I will try to turn off HDR because some programmer type people have told me that HDR is likely the problem. If it is the problem they said they would mod the psys file so I can still use HDR and not have the explosions cause such fps problems. How many of you use HDR and do any of you that have smooth FPS during explosions have it on and have you looked at 2 b52’s dropping 40-50 bombs from angels 20-30? I use Vsync but I will be doing further testing with it off.

Drop from explosions is normal, but mainly if you look from close… from A29 I wouldn’t expect such loss of frame rate, it could be related to something else. Also are u running with V-Sync on? Cause that might be a reason for lower FPS…
I also STRONGLY suggest you and everyone to not force AA from driver level and use the built-in Multi-Sampling in BMS UI setting. Quality 3-4 should be enough for high quality picture.
I just finished testing and I turned everything off to start except for shaders all together. I tried reduced particle system.
vsync-off
AA-off
TMAA-off
AF-off
Ambient Occlusion-off
HDR-offI had an average of 130 fps, max 170 fps, and over 80 with TGP on. I flew the mission with no problems until the bombs hit the deck and I looked at them. FPS dropped to 30. This is unacceptable to me and aside from turning shaders off completely I do not know what else to do except just deal with it. I didn’t have this problem in 4.33. I had lower avg FPS but never had this problem. If I can’t fix it by turning everything off then I may as well turn everything back on because I have no problems until the smoke on the ground starts. Either way it is a problem so I may as well not suffer during the flight with low settings just to suffer anyways when the bombs hit. A 100 FPS drop is ridiculous for a few explosions. That is over a 75% drop in FPS.

Hi,
Please take a vid of the FPS drop you are talking about. If you are looking at 40-50 MK-82/84 bombs exploding at same area then yes you are expected to have a serious drop in FPS, how serious? depends on your V-Card… I can estimate that if I looked at such event, my FPS would cut by half here… I think it is sane considering the amount of particles generated during so many explosions.
Particle system is using a lot of polys on top of each other in order to create 3Dness look to the fire/smoke, and all polys are textured with DXT5 transparent textures and blending is enabled… so V-Card is working pretty hard to calculate the color at each pixel, and so you are getting FPS hit. I can show you how I can cripple ANY video card if I generate enough particles in BMS…
I say as long as the FPS are dropping only for the time the heavy explosions are on, you should be OK as it doesn’t happen so much during campaigns.

Well a b-52 ain’t causing a “few” explosions but maybe it is causing the most demanding explosions after the nukes.

They only dropped maybe 10-20 bombs on the first run and I was at angels 25-30. It still dropped the FPS down. I also tried a mav run and it did the same but not as bad. It also happens when I drop 4 cbu’s and especially if I’m carrying a load of rockeyes. If I drop the cbu’s then pull up and look back for a BDA it drops almost as bad as the B-52. I am finding out that it is not too unusual and is part of how the sim works. I am fine with it and will adjust my missions accordingly. I just don’t want to settle for something that is not supposed to be happening. The part that confuses me is that with all the setting at off or minimum I get about the same performance as when I have them nearly maxed out. It doesn’t help the slow down with ground explosion smoke. With my settings near max it actually runs smoother and is less choppy as well as less noticeable when the slowdowns happen.

OK. Thanks I-Hawk
I was hoping that a setting like reduced particles or something would get rid of it. I would be OK with it looking a bit less dramatic if it would not slow down as much. When I saw a flight escorting the B-52’s I was excited and it kind of bummed me out that right when my work was paying off and the 52’s were dropping their bombs, I looked and bam FPS in the teens. Thanks for the explanation.
I will take a vid but I have never recorded before. The only program I have that I know of that records vids is on Steam called shadowplay. If that works, I will try to use that. I just have to figure out how to use it and see if it works to record non steam games.

They? like there was more than one? so 10-20 each so 20-40 bombs in total?
And IIRC they maybe drop more than 20 each. -
You can use OBS to record a vid, but note that recording will also eat some FPS.

And IIRC they maybe drop more than 20 each.10 to 20 bombs total. 2 B-52’s. One time they only got a few off then stopped. I don’t know why. I got to the target really early and waited for them and they flew in and I think one dropped less than 5 bombs then just did the usual AI fly around thing.

For Nvidia users - in Nvidia Inspector you can try to set Texture filtering - Quality to High Performance and fps hit is quite reduced, at least on my system (single monitor, low res 1680x1090). No dramatic effect on quality of visuals.
